Syntax error Ints concat() function in Java

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 < myArr1.length; i++) {
         System.out.println(myArr1[i]);
      }
      System.out.println("Array 2 = ");
      for(int i=0; i < myArr2.length; i++) {
         System.out.println(myArr2[i]);
      }
      int[] arr = Ints.concat(myArr1, myArr2);
      System.out.println("Concatenated arrays = "+Arrays.toString(arr));
   }
}

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]
