Question

我无法弄清楚为什么eclipse要我删除“;”并用“，”替换它。

numberOfTimes1 = numberOfTimes + numberOfDelayTimes;

我猜这是我忘记的一些简单的语法。你能解释它为什么这样做以及如何解决它。整个计划

public class Spam {


    public static void main(String[] args) {
        //1- Taking an instance of Timer class.
        Timer timer = new Timer("Printer");

        //2- Taking an instance of class contains your repeated method.
        timeso t = new timeso();

        timer.schedule(t, 0, 10);
    }

}
class timeso extends TimerTask {
    //times member represent calling times.
    private int times = 0;
    int time = 6; //How long do you wish for the spamming to run?
    int numberOfTimes = time * 100;
    int delayTime = 5; //How long do you wish for the program to wait before spamming?
    int numberOfDelayTimes = delayTime * 100;
    numberOfTimes = numberOfTimes + numberOfDelayTimes;
    String spam;
    Random randomGenerator = new Random();

    public void run() {
        times++;
        if (times >= numberOfDelayTimes && times <= numberOfTimes+numberOfDelayTimes) {

            try {
                Robot typer = new Robot();
                //for(int x = 1;x <=randomGenerator.nextInt(5); x++){
                //  spam = spam + randomGenerator.nextInt(10);
                //}
                byte[] bytes = "spam".getBytes();

                    int code = b;
                    // key code only handles [A-Z] (which is ASCII decimal [65-90])
                    if (code > 96 && code < 123) code = code - 32;
                    typer.delay(10/bytes.length+1);

                if(times % (randomGenerator.nextInt(25)+1) == 0){

你试图在方法或构造函数之外调用一行代码，这就是Java编译器（而不是Eclipse）抱怨的原因。在构造函数或方法中执行那种代码，而不是在类中裸。实际上，你的timeso类中的所有代码都是错误的，需要在方法或构造函数中。

注意：您将学习Java命名约定并坚持使用它，包括使用大写字母和方法启动类名以及使用小写字母的变量名。这样做有助于其他人（我们！）更好地理解您的代码。
