6. 2차원 배열 정리

1. 2차원 배열 생성하기

int[][] arr1 = new int[2][1];
arr1[0][0] = 1;
arr1[1][0] = 2;
System.out.println(Arrays.deepToString(arr1));

int[][] arr2 = new int[2][1];
arr2[0][0] = 3;
arr2[1][0] = 4;

 

 

 

2. 2차원 배열 출력하기

int[][] arr1 = new int[2][1];
arr1[0][0] = 1;
arr1[1][0] = 2;
System.out.println(Arrays.deepToString(arr1));

int[][] arr2 = new int[2][1];
arr2[0][0] = 3;
arr2[1][0] = 4;

System.out.println(Arrays.deepToString(arr2));
