What it does

Pseudocode To Java Code is an agent skill from ArabelaTso/Skills-4-SE. Converts pseudocode descriptions and algorithm specifications into complete, executable Java code. Use this skill when you need to implement algorithms from pseudocode, translate algorithm descriptions to Java, generate Java code from specifications, convert textbook algorithms to working code, or create executable implementations from high-level descriptions. Preserves logic and control flow while handling Java idioms, data structures, and includes test cases for verification.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files and assets (for example `references/mapping_patterns.md`).

It sits in Testing & QA, covering Test generation. It works with Java. The repository describes itself as: A curated list of 180+ useful Claude Skills for Software Engineering and resources for customizing AI for SE workflows. The licence is Apache-2.0.

When your agent uses it

  • You need to implement algorithms from pseudocode
  • Translate algorithm descriptions to Java
  • Generate Java code from specifications
  • Convert textbook algorithms to working code

Example prompts

  • “Use the pseudocode-to-java-code skill to convert pseudocode descriptions and algorithm specifications into complete, executable Java code”
  • “/pseudocode-to-java-code”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Provide Pseudocode Input
  2. Specify Requirements (Optional)
  3. Generate Java Code
  4. Review Mapping Summary
  5. Test and Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 4f38503. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Java), which the agent can run.

    Shell commands in SKILL.md call:

    • javac
    • java

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pseudocode To Java Code loads about 1.9k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 127 tokens; SKILL.md has 466 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~127
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Pseudocode to Java Code

Overview

This skill converts pseudocode descriptions and algorithm specifications into complete, executable Java programs. It preserves the original logic and control flow, applies appropriate Java idioms and data structures, and generates test cases to verify correctness.

Workflow

1. Provide Pseudocode Input

Give the pseudocode or algorithm specification. Formats accepted:

  • Structured pseudocode with keywords (IF, FOR, WHILE, etc.)
  • Algorithm descriptions in plain text
  • Textbook-style algorithm specifications
  • Flowchart-like descriptions

Example:

FUNCTION findMax(array)
    max ← array[0]
    FOR i FROM 1 TO LENGTH(array) - 1 DO
        IF array[i] > max THEN
            max ← array[i]
        END IF
    END FOR
    RETURN max
END FUNCTION
2. Specify Requirements (Optional)

Provide additional context:

  • Expected input/output types
  • Performance requirements
  • Specific Java version or features to use
  • Edge cases to handle
  • Naming preferences
3. Generate Java Code

The skill will produce:

  • Complete Java class with proper structure
  • Converted algorithm as Java method(s)
  • Appropriate data structures and types
  • Necessary imports
  • Main method with test cases

Output Example:

java
import java.util.*;

public class ArrayMaxFinder {

    public static void main(String[] args) {
        ArrayMaxFinder solution = new ArrayMaxFinder();

        // Test case 1: Normal array
        int[] arr1 = {3, 7, 2, 9, 1};
        System.out.println("Max: " + solution.findMax(arr1)); // Expected: 9

        // Test case 2: Single element
        int[] arr2 = {5};
        System.out.println("Max: " + solution.findMax(arr2)); // Expected: 5
    }

    /**
     * Finds the maximum value in an array
     * @param array the input array
     * @return the maximum value
     */
    public int findMax(int[] array) {
        int max = array[0];
        for (int i = 1; i < array.length; i++) {
            if (array[i] > max) {
                max = array[i];
            }
        }
        return max;
    }
}
4. Review Mapping Summary

The skill provides a summary explaining:

  • How pseudocode constructs map to Java
  • Data structure choices
  • Type decisions
  • Any assumptions made

Example Summary:

Mapping Summary:
- FUNCTION → public method
- array parameter → int[] array
- LENGTH(array) → array.length
- FOR loop → standard Java for loop
- IF condition → if statement
- RETURN → return statement
- Added null/empty array handling
- Included test cases for verification
5. Test and Verify

Run the generated code:

bash
javac ArrayMaxFinder.java
java ArrayMaxFinder

Verify output matches expected results.

Common Conversions

Control Structures

IF-ELSE:

Pseudocode: IF condition THEN ... ELSE ... END IF
Java: if (condition) { ... } else { ... }

FOR Loop:

Pseudocode: FOR i FROM 1 TO n DO ... END FOR
Java: for (int i = 1; i <= n; i++) { ... }

WHILE Loop:

Pseudocode: WHILE condition DO ... END WHILE
Java: while (condition) { ... }
Data Structures

Array:

Pseudocode: DECLARE array[n] OF INTEGER
Java: int[] array = new int[n];

List:

Pseudocode: DECLARE list AS LIST OF INTEGER
Java: List<Integer> list = new ArrayList<>();

Map:

Pseudocode: DECLARE map AS MAP FROM STRING TO INTEGER
Java: Map<String, Integer> map = new HashMap<>();

Set:

Pseudocode: DECLARE set AS SET OF INTEGER
Java: Set<Integer> set = new HashSet<>();
Operations

String Operations:

  • LENGTH(string) → string.length()
  • SUBSTRING(string, start, end) → string.substring(start, end)
  • CONCATENATE(str1, str2) → str1 + str2

Math Operations:

  • POWER(base, exp) → Math.pow(base, exp)
  • SQRT(value) → Math.sqrt(value)
  • MAX(a, b) → Math.max(a, b)

Advanced Features

Generic Types

When pseudocode uses generic collections:

Pseudocode: DECLARE list AS LIST OF TYPE
Java: List<T> list = new ArrayList<>();
Exception Handling

Add appropriate exception handling:

java
try {
    // algorithm implementation
} catch (ArrayIndexOutOfBoundsException e) {
    // handle error
}
Optimization

Apply Java-specific optimizations:

  • Use StringBuilder for string concatenation
  • Use enhanced for loops where appropriate
  • Apply stream operations for functional style

Limitations

  1. Ambiguous Types: May need clarification for ambiguous pseudocode types

  2. Complex Data Structures: Custom data structures may need additional specification

  3. Concurrency: Pseudocode doesn't usually specify thread safety

  4. I/O Operations: File/network operations need additional context

  5. Language Features: Some pseudocode constructs may not have direct Java equivalents
