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 stringsSystem.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 arraySystem.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 stringsfor (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 orderSystem.out.print("Strings in Sorted Order:");for (int i = 0; i <= count - 1; i++){System.out.print(str[i] + ", ");}}}
输出:
