}

}

public static void main(String[] args) { }

Print(sort); Sort(sort); Print(sort);

System.out.println(count);

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

System.out.print('\n');

System.out.print(sort[i]); System.out.print(" ");

运行结果是：

2． 程序如下：

public class shiyan2_ti2 {

public static void Print(int [][] matrix) { }

public static void main(String [] args) {

int [][] matrix = {{1,3,4},

{2,3,4},

int sum = 0;

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

System.out.println(sum);

sum += matrix[i][i];
