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:

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;
    }
}
