Guava’s Ints.concat() method is used to combine the arrays passed as parameters into a single array. This method returns the values from each provided array combined into a single array. For example, concat(new int[] {a, b}, new int[] {}, new int[] {c} returns the array {a, b, c}.
Syntax:
public static int[] concat(int[]... arrays)
Parameters: This method takes arrays as parameter which represents zero or more int arrays.
Return Value: This method returns a single array containing all the values from the source arrays, in order.
Example 1:
// Java code to show implementation of// Guava's Ints.concat() method import com.google.common.primitives.Ints;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating 2 Integer arrays int[] arr1 = { 1, 2, 3, 4, 5 }; int[] arr2 = { 6, 2, 7, 0, 8 }; // Using Ints.concat() method to combine // elements from both arrays into a single array int[] res = Ints.concat(arr1, arr2); // Displaying the single combined array System.out.println("Combined Array: " + Arrays.toString(res)); }} |
Output:
Combined Array: [1, 2, 3, 4, 5, 6, 2, 7, 0, 8]
Example 2:
// Java code to show implementation of// Guava's Ints.concat() method import com.google.common.primitives.Ints;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating 4 Integer arrays int[] arr1 = { 1, 2, 3 }; int[] arr2 = { 4, 5 }; int[] arr3 = { 6, 7, 8 }; int[] arr4 = { 9, 0 }; // Using Ints.concat() method to combine // elements from both arrays into a single array int[] res = Ints.concat(arr1, arr2, arr3, arr4); // Displaying the single combined array System.out.println("Combined Array: " + Arrays.toString(res)); }} |
Output:
Combined Array: [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
