冒泡排序

public static void bubbleSort(int []arr) {
for(int i =0;i<arr.length-1;i++) {
for(int j=0;j<arr.length-i-1;j++) { //-1为了防止溢出
if(arr[j]>arr[j+1]) { //把大的数放在后面
int temp = arr[j];
arr[j]=arr[j+1];
arr[j+1]=temp;
}
}
}
}

2. 希尔排序

public static void main(String [] args)
{
int[]a={49,38,65,97,76,13,27,49,78,34,12,64,1};
//希尔排序
int d=a.length;
while(true){
d=d/2;
for(int x=0;x<d;x++){
for(int i=x+d;i<a.length;i=i+d){
int temp=a[i];
int j;
for(j=i-d;j>=0&&a[j]>temp;j=j-d){
a[j+d]=a[j];
}
a[j+d]=temp;
}
}
if(d==10){
break;
}
}
}

1、九九乘法表
public class convert {
public static void main(String[] args) {
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(i+"*"+j+"="+j*i+"");
}
System.out.print("\n");
}
}
}
2、冒泡排序

public static void bubbleSort(int[] numbers){
int temp = 0;
int size = numbers.length;
for(int i = 0 ; i < size-1; i ++){
for(int j = 0 ;j < size-1-i ; j++){
if(numbers[j] > numbers[j+1]) //交换两数位置 {
temp = numbers[j];
numbers[j] = numbers[j+1];
numbers[j+1] = temp;
}
}
}
}
