冒泡排序:
public class BubbleSort {
public static void main(String[] args) {
sort(new int[] { 5, 3, 2, 9, 2, 0, 4 });
}
public static void sort(int[] a) {
int temp = 0;
for (int i = a.length - 1; i > 0; --i) {
for (int j = 0; j < i; ++j) {
if (a[j + 1] < a[j]) {
temp = a[j];
a[j] = a[j + 1];
a[j + 1] = temp;
}
}
}
}
