Question

在java中如何将一个5*3的二维数组转置输出

Answer 1

效果如图

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

public class TestArray {

public static void method(int[][] array) {

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

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

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

}

System.out.println();

}

}

public static void main(String args[]) {

int[][] array={{1,2,3},{1,2,3},{1,2,3},{1,2,3},{1,2,3}};

method(array);

}

}

Answer 4

可以如下操作：

int[][] num = new int [5][3];
//num为5*3的二位数组

init(num);
//为num数组负值

for(int i=0;i<3;i++)
{
for(int j=0;j<5;j++)
{
System.out.print(num[j][i]);
System.out.print(" ");
}
System.out.print("\n");
}
//双重for循环实现二维数组的转置输出

That's all.
