解决java的非法字符: ‘\u200b‘的问题

1.将原代码拷贝到notepad++

public class HelloFiber {

    public static void main(String[] args) throws  Exception {
        long start = System.currentTimeMillis();
        Runnable r = new Runnable() {
            @Override
            public void run() {
                calc();
            }
        };

        int size = 10000;

        Thread[] threads = new Thread[size];
        for (int i = 0; i < threads.length; i++) {
            threads[i] = new Thread(r);
        }

        for (int i = 0; i < threads.length; i++) {
            threads[i].start();
        }

        for (int i = 0; i < threads.length; i++) {
            threads[i].join();
        }

        long end = System.currentTimeMillis();
        System.out.println(end - start);


    }

    static void calc() {
        int result = 0;
        for (int m = 0; m < 10000; m++) {
            for (int i = 0; i < 200; i++) result += i;

        }
    }
}

2.按ctrl+F进行替换

选中扩展模式，将\u200b替换为空白
