arrayofarraysdemo2.java

我自己学习JAVA过程中用键盘敲的代码

package jerryhfb;
public class ArrayOfArraysDemo2 {

public static void main(String[] args) {

int[][] aMatrix = new int[4][];

for (int i = 0; i < aMatrix.length; i++) {

aMatrix[i] = new int[5]; //create sub-array

for (int j = 0; j < aMatrix[i].length; j++) {

aMatrix[i][j] = i + j;

}

}

//打印

for (int i = 0; i < aMatrix.length; i++) {

for (int j = 0; j < aMatrix[i].length; j++) {

System.out.print(aMatrix[i][j] + " ");

}

System.out.println();

}

}

}
