随机生成整数 然后对其排序（冒泡法）

import java.util.Scanner;

public class random {
public static void whileTest() {
int temp = 0;
int i, j;
System.out.println("请输入你要随机生成的个数:");
Scanner shuru = new Scanner(System.in);
int shuru1 = shuru.nextInt();
int sum[] = new int[shuru1];
System.out.println("随机生成10个整数型的数:");
for (i = 0; i < sum.length; i++) {
sum[i] = (int) (Math.random() * 100);
System.out.print(sum[i] + "  ");
}
for (i = 0; i < sum.length; i++) {
for (j = i + 1; j < sum.length; j++) {
if (sum[i] > sum[j]) {
temp = sum[i];
sum[i] = sum[j];
sum[j] = temp;
}
}
}
System.out.println();
System.out.println("排序后的结果:");

for (i = 0; i < sum.length; i++) {
System.out.print(sum[i] + "  ");
}
/*
* boolean result = Math.random() < 0.9; System.out.println(result +
* "."); // static定义的方法只 return result;
*/
}

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