Java 程序按字母顺序对字符串进行排序

编写一个 Java 程序，按字母顺序对字符串进行排序。此示例允许输入大小和字符串项。接下来，我们使用 Array sort 函数按字母顺序对单词或字符串数组进行排序。

package RemainingSimplePrograms;

import java.util.Arrays;

import java.util.Scanner;

public class SortStringArrAlphabetically1 {
	private static Scanner sc;
	private static Scanner sc2;
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);
		sc2 = new Scanner(System.in);
		
		System.out.print("Enter the Total Strings you enter = ");
		int Size = sc.nextInt();
		
		String str[] = new String[Size];
		
		System.out.format("Enter %d Strings one by one\n", Size);
		for(int i = 0; i < Size; i++) 
		{
			str[i] = sc2.nextLine();
		}
		
		Arrays.sort(str);
		
		System.out.format("\nAfter Sorting the String Alphabetically\n");
		for(String s: str) 
		{
			System.out.print(s + "  ");
		}
	}
}

使用 for 循环按字母顺序对字符串进行排序的 Java 程序

在此 示例 中，我们使用 for 循环从头到尾迭代字符串数组，并比较每个单词。我们使用临时变量根据结果移动它们的位置。

package RemainingSimplePrograms;

import java.util.Scanner;

public class Example2 {
	private static Scanner sc;
	private static Scanner sc2;
	public static void main(String[] args) {
		int Size, i, j;
		String temp;
		
		sc = new Scanner(System.in);
		sc2 = new Scanner(System.in);
		
		System.out.print("Enter the Total Words you enter = ");
		Size = sc.nextInt();
		
		String str[] = new String[Size];
		
		System.out.format("Enter %d Sentences one by one\n", Size);
		for(i = 0; i < Size; i++) 
		{
			str[i] = sc2.nextLine();
		}
		
		for(i = 0; i < Size; i++) 
		{
			for(j = i + 1; j < Size; j++)
			{
				if(str[i].compareTo(str[j]) > 0)
				{
					temp = str[i];
					str[i] = str[j];
					str[j] = temp;
				}
			}
		}
		
		System.out.format("\nAfter Sorting the String Alphabetically\n");
		for(i = 0; i < Size; i++) 
		{
			System.out.print(str[i] + "  ");
		}
	}
}
