挺简单的一个题。

源码

package 字符串对比;

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		
		Scanner scanner = new Scanner(System.in);
		String string1 = scanner.next();
		String string2 = scanner.next();
		
		if(string1.equals(string2)){
			System.out.println("2");
		}
		
		if(string1.length()!=string2.length()){
			System.out.println("1");
		}
		
		
		if(string1.length() == string2.length()){
			boolean ans = true;
			for(int i = 0; i < string1.length(); i++){
				int temp = string1.charAt(i)-string2.charAt(i);
				if(temp != 0 && Math.abs(temp) != 32 ){
					ans = false;
				}
			}
			
			if(string1.equals(string2)){
				
			}else{
				if(ans){
					System.out.println("3");
				}else{
					System.out.println("4");
