There are several ways to print an array in Java. Here are a few options: Using a loop: int[] array = {1, 2, 3, 4, 5}; for (int i = 0; i < array.length; i++) { System.out.print(array[i] + " "); } Using the Arrays.toString() method: import java.util.Arrays; ...
JavaObject Oriented ProgrammingProgramming You can simply iterate the byte array and print the byte using System.out.println() method. Example public class Tester { public static void main(String[] args) { byte[] a = { 1,2,3}; for(int i=0; i< a.length ; i++) { System.out.print...
public class Print2DArray { public static void main(String[] args) { final int[][] matrix = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; for (int i = 0; i < matrix.length; i++) { //this equals to the row in our matrix. for (int j = 0; j < matrix[i]...
int[][]multiArray={{2,7,9}, {3,6,1}, {7,4,2}};for(inti=0;i<3;i++){for(intj=0;j<3;j++)System.out.print(multiArray[i][j]+" ");System.out.println();} 输出 279361742 多维数组 传递数组 像变量一样,数组也可以传递进入方法中。
