arrayofarraysdemo2.java

我在学习JAVA的讲义

public class ArrayOfArraysDemo2 { 
	public static void main(String[] args) { 
		int[][] aMatrix = new int[4][]; 
		//populate matrix 
		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; 
			} 
		} 
		//print matrix 
		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(); } 
	}
 }
