Java 我似乎为我的简单计数器程序做了所有正确的事情，但是当我在命令行上运行程序时，什么都没有发生

我做了一个简单的计数器程序。它数到100。给你

class counter {

public static void main(String args[]) {
    int count;

    count = 0;

    for (count = 0; count <= 99; count++) {
        System.out.println("count " + count);
    }
    if (count == 100) {
        System.out.println("final count " + count);
    }
}
}

类计数器{
公共静态void main（字符串参数[]）{
整数计数；
计数=0；
对于（count=0；count，您的课程是正确的

将其放入名为counter.java的文件中

编译它

$ javac counter.java 

$ java counter
