Java method example for initializing and filling arrays

Initialize and populate the array

import java.util.Arrays;

public class ArrayFilling {

 public static void main(String[] args) {

 int[] scoreArr = new int[8]; // 创建一个大小为8的数组

 Arrays.fill(scoreArr,0); // 将数组使用数字 0 进行填充

 for (int i = 0; i < scoreArr.length; i++) {
  System.out.print(scoreArr[i] + " ");
 }
        System.out.print("");
 Arrays.fill(scoreArr,2,6,1);// 将索引从 2 到 6 使用数字 1 进行填充
 for (int i = 0; i < scoreArr.length; i++) {
  System.out.print(scoreArr[i] + " ");
 }
 }
}

Print results:

PS: array filling in Java

Through the array of the Java uill class. Fill (array name, value) method and array Fill (arrayname, starting index, ending index, value) code:

import java.util.Arrays;

public class ArrayFill {

 public static void main(String[] args) {
 int array[] = new int[6];
 Arrays.fill(array,100);
 for (int i = 0;i < array.length; i++) {
  System.out.print(array[i]+" ");
 }
 System.out.println();
 Arrays.fill(array,3,50);
 for (int i = 0; i < array.length; i++) {
  System.out.print(array[i]+" ");
 }
 }

}

result:
