java数组是基础数据类型_java——基础数据类型——数组操作—— 遍历数组

package jkcs;

public class jblx

{

public static void main(String[] args)

{

// TODO Auto-generated method stub

// TODO Auto-generated method stub

int a[][] = new int[][]{{1},{2,3},{4,5,6}}; //初始化一个数组

System.out.println("-------------------");

System.out.println(a.length); //3

System.out.println("-------------------");

System.out.println(a[0].length); //1

System.out.println(a[1].length); //2

System.out.println(a[2].length); //3

System.out.println("-------------------");

System.out.println(a[0][0]);

System.out.println(a[1][0]);

System.out.println(a[1][1]);

System.out.println(a[2][0]);

System.out.println(a[2][1]);

System.out.println(a[2][2]);

System.out.println("-------------------");

for ( int k = 0;k

{

for( int j=0;j

{

System.out.print(a[k][j]+"--------");

}

}

}

}

执行结果：

-------------------

3

-------------------

1

-------------------

-------------------
