Java 实例 按字母顺序排序字符串

在这个 java 教程中，我们将学习如何按字母顺序对字符串进行排序。

Java 示例：按字母顺序排列字符串

在这个程序中，我们要求用户输入他想要输入的字符串计数以进行排序。一旦使用Scanner类捕获计数，我们已初始化输入计数大小的String数组，然后运行for循环以捕获用户输入的所有字符串。

一旦我们将所有字符串存储在字符串数组中，我们就会比较每个字符串的第一个字母，以便按字母顺序对它们进行排序。

import java.util.Scanner;public class JavaExample{    public static void main(String[] args)     {        int count;        String temp;        Scanner scan = new Scanner(System.in);        //User will be asked to enter the count of strings         System.out.print("Enter number of strings you would like to enter:");        count = scan.nextInt();        String str[] = new String[count];        Scanner scan2 = new Scanner(System.in);        //User is entering the strings and they are stored in an array        System.out.println("Enter the Strings one by one:");        for(int i = 0; i < count; i++)        {            str[i] = scan2.nextLine();        }        scan.close();        scan2.close();        //Sorting the strings        for (int i = 0; i < count; i++)         {            for (int j = i + 1; j < count; j++) {                 if (str[i].compareTo(str[j])>0)                 {                    temp = str[i];                    str[i] = str[j];                    str[j] = temp;                }            }        }        //Displaying the strings after sorting them based on alphabetical order        System.out.print("Strings in Sorted Order:");        for (int i = 0; i <= count - 1; i++)         {            System.out.print(str[i] + ", ");        }    }}

输出：
