Java冒泡排序法：

例：

public static void main(String[] args) {

int[] a = {3,1,4,22,0};

for (int i = 0; i < a.length-1;i++) {

for (int j = 0; j < a.length-1-i;j++) {

if (a[j] > a[j+1]) {

int tmp = a[j];

a[j] = a[j+1];

a[j+1] = tmp;

}

}

}

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

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

}

}
