java实现的各种排序~

public class SortClass {

public static void main(String[] args) {
int[] array ={2,4,3,56,1,23};
for(int i=0;i<array.length;i++){
for(int j=0;j<array.length;j++){
if(array[i]<array[j]){
int temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}
}
// 打印
for (int i = 0; i < array.length; i++) {
System.out.print(array[i] + " ");
}
}
}

public static void main(String[] args) {
/**
* 冒泡排序
*/
int[] arr = { 3, 6, 8, 74, 99, 12 };

for (int i = 0; i < arr.length - 1; i++) {
// 每一次比较的元素-1，避免角标越界
for (int j = 0; j < arr.length - i - 1; j++) {
if (arr[j] < arr[j + 1]) {
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
// 输出
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + " ");
}

}
