[Java] 数组排序和字符串排序

 

方法1

public class Sort
{
	public static void main(String[] args)
	{
		int[] num1 = {4,3,2,-2,-8,55,33,24,56,23,65,88,457,-23,-66};
		sort(num1);
	}

	public static void sort(int[] num)
	{
		int j=0;
		while(j<num.length)
		{
			for(int i=0;i<num.length-1;i++)
			{
				if(num[i]>num[i+1])
				{
					int temp;
					temp = num[i];
					num[i]=num[i+1];
					num[i+1]=temp;
				}
			}
			j++;
		}
		for(int i=0;i<num.length;i++)
		{
			System.out.print(num[i]+"	");
		}
	}
}

 

方法2:

import java.util.Arrays;
public class Sort2
{
	public static void main(String[] args)
	{
		int[] num = {4,3,2,-2,-8,55,33,24,56,23,65,88,457,-23,-66};
		Arrays.sort(num);
		for(int i : num)
		{
			System.out.print(i+ " ");
		}
		
		System.out.println();
		String[] str = {"Mike","Jerry","Tom","Lucy","Lily","Auther","Yoyo"};
		Arrays.sort(str);
		for(String s : str)
		{
			System.out.print(s + " ");
		}
	}
