那位大侠能帮我改改吗？

看你这程序写的……去掉没用的语句，整个程序就这么几行：

import java.util.Scanner;

public class MyStringBuffer {
    public static void main (String[] args) {
        Scanner s = new Scanner(System.in);
        String str1 = s.next();
        String str2 = s.next();
        
        if (str1.equalsIgnoreCase(str2))
            System.out.println("stringbuffer1 equals to stringbuffer2");
        else
            System.out.println("stringbuffer1 does not equal to stringbuffer2");
    }
}

给你的意见：
1）多余的语句一句都不要写
2）缩进什么的都对齐了
3）学会写注释

再给你压缩一下：

import java.util.Scanner;

public class MyStringBuffer {
    public static void main (String[] args) {
        Scanner s = new Scanner(System.in);
        
        if (s.next().equalsIgnoreCase(s.next()))
            System.out.println("stringbuffer1 equals to stringbuffer2");
        else
            System.out.println("stringbuffer1 does not equal to stringbuffer2");
    }
}

再压缩一下：

import java.util.Scanner;

public class MyStringBuffer {
    public static void main (String[] args) {
        Scanner s = new Scanner(System.in);
        System.out.println((s.next().equalsIgnoreCase(s.next()) ? "stringbuffer1 equals to stringbuffer2" : "stringbuffer1 does not equal to stringbuffer2");
    }
}

你的 26 行代码，实质上 = 我的 7 行代码
