Description

Copy an array of signed values in int, into an array of short. The value is truncated as necessary.

Demo Code

//package com.java2s;

public class Main {
    public static void main(String[] argv) throws Exception {
        int[] src = new int[] { 34, 35, 36, 37, 37, 37, 67, 68, 69 };
        System.out.println(java.util.Arrays
                .toString(copySignedIntToShortArray(src)));
    }/* ww  w .ja  v a 2s. c o m*/
