over.java

JAVA写的一个排序的实验.比较简单.适合初学.

class ThreeSort
{
	public void sort(int a,int b)
  	{
     		if(a<b)
     		{
         		System.out.println(a);
         		System.out.println(b);
     		}
     	else
    	{  
      	 	System.out.println(b);
      	 	System.out.println(a);
    	}
 }

public void sort(int a,int b,int c)
{
  	if(a<b && a<c)
  	{
   		System.out.println(a);
   		if(b<c)
   		{
    			System.out.println(b);
    			System.out.println(c);
   		}
   		else
   		{
			System.out.println(c);
			System.out.println(b);
		}
	}
	else
	{
		if(b<a && b<c)
		{
			System.out.println(b);
			if(a<c)
			{
				System.out.println(a);
				System.out.println(c);
			}
			else
			{
     				System.out.println(c);
     				System.out.println(a);
    			}
   		}
   		else
   		{		
    			System.out.println(c);
    			if(a<b)
    			{
     				System.out.println(a);
     				System.out.println(b);
    			}
    			else
    			{
    				System.out.println(b);
     				System.out.println(a);
    			}
   		}
  	}
}

 public void sort (int arr[])
 { 
  int n = arr.length;
  int temp;
  for(int i = 0;i < n;i++)
  {
   for(int j = 0;j < n-1-i;j++)  //排序
   {
    if(arr[j]>arr[j+1])
    {
     temp = arr[j+1];
     arr[j+1] = arr[j];
     arr[j] = temp;
    }
   }
   

  }
  for(int k = 0 ; k < n ; k++)
  {
   System.out.println(arr[k]);
  }
 }

}
