Ints concat() function in Java

The concat() function in Ints class is used to concatenate the arrays passed as parameter. The syntax is as follows −

public static int[] concat(int[]... arr)

Here, parameter arr is zero or more integer arrays.

Let us see an example −

Example

import com.google.common.primitives.Ints;
import java.util.*;
class Demo {
   public static void main(String[] args) {
      int[] myArr1 = { 100, 150, 230, 300, 400 };
      int[] myArr2 = { 450, 550, 700, 800, 1000 };
      System.out.println("Array 1 = ");
      for(int i=0; i 
Output
Array 1 =
100
150
230
300
400
Array 2 =
450
550
700
800
1000
Concatenated arrays = [100, 150, 230, 300, 400, 450, 550, 700, 800, 1000]
