按字母顺序排列字符串的Java程序

编写一个Java程序，按字母顺序对字符串进行排序。这个Java例子允许输入大小和字符串项。接下来，我们使用Java数组排序功能，按字母顺序对单词或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循环对字符串按字母顺序排序的Java程序

在这个Java例子中，我们使用for循环从头到尾遍历字符串数组，并将每个词与另一个词进行比较。我们使用temp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\[i\] + "  ");
	}
}
