COMPLETE JAVA 17 PROGRAM

Complete Java 17 implementation

class Main {
    static int search(int[] a,int target,int low,int high){if(low>high)return -1;int mid=(low+high)/2;if(a[mid]==target)return mid;return a[mid]<target?search(a,target,mid+1,high):search(a,target,low,mid-1);}
    public static void main(String[] args) {
        int[] values={2,5,8,12,16};
        System.out.println(search(values,12,0,values.length-1));
    }
}

PROGRAM EXPLANATION

Algorithm and explanation

1. Initialize the deterministic sample values used for perform recursive binary search in java.
2. Apply Binary search and Recursion in the order shown by the program.
3. Print the final result and compare it with the documented sample output.

This Java 17 example demonstrates Binary search and Recursion through a complete, executable program. The values are intentionally small so students can trace each statement, verify the output, and then modify the example safely in the online compiler.
