view plaincopy to clipboardprint?

import java.util.*;

public class ForeachExample {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

Random r = new Random();

int[] x = new int[10];

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

x[i] = r.nextInt(100);

}

// foreach的使用

for (int y : x) {

System.out.print(y + " ");

}

System.out.println();

// 另一种打印数组的方式

System.out.println(Arrays.toString(x));

for (char c : "I am a good girl!".toCharArray())

System.out.print(c + " ");

}

}
