Thread: how to add a new entry in a current array

a liitle bit of program that demonstrates how to add a new entry in a current array that has current values

public class ArraySampleExtendingIndex {
 
    private static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        System.out.print("[");
 
        // display the current values
