创建一维二维数组以及输出

//import java.util.Scanner;

public class Code9_5 {
    public static void main(String[] args){
        //一维数组
        int[] a=new int[10];
        //二维数组
        int[][] b={{1,2},{2,3},{3,4},{4,5}};
        for (int i=0;i<=9;i++)
        System.out.println(a[i]+" ");
        for (int i=0;i<=3;i++)
            for (int j=0;j<=1;j++)
            System.out.println(b[i][j]+" ");
    }

}
