苦恼的java问题~~

[davidtps]

源码是：
public class TestThread {
public static void main(String [] args) {
Runner1 r1 = new Runner1();
Thread td = new Thread(r1);
td.start();

for (int j = 1; j < 100 ;j++ ){
System.out.println("Thread :" + j);
}

}

class Runner1 implements Runnable{
public void run () {
for (int i = 0; i<100 ;i++ ){
System.out.println("runner1:" + i);
}
}
}


}


错误是：

D:\Test>javac TestThread.java
TestThread.java:4: 无法从静态上下文中引用非静态 变量 this
Runner1 r1 = new Runner1();
^
1 错误


请问是哪出错了啊~~~~~~~~~~

public class TestThread {

	public void test() {
		Runner1 r1 = new Runner1();
		Thread td = new Thread(r1);
		td.start();

		for (int j = 1; j < 100; j++) {
			System.out.println("Thread :" + j);
		}
	}

	public static void main(String[] args) {
		TestThread testThread = new TestThread();
		testThread.test();

	}

	class Runner1 implements Runnable {
		public void run() {
			for (int i = 0; i < 100; i++) {
				System.out.println("runner1:" + i);
			}
		}
	}

}

楼主帮你改好了，看上面。

楼上 很热心~ 我怎么是恶意灌水了呢

直接将class Runner1 implements Runnable 改成static class Runner1 implements Runnable前面加个STATIC 即可

[lvzhu18]

public class TestThread {
	public static void main(String[] args) {
		Runner1 r1 = new TestThread().new Runner1();
		Thread td = new Thread(r1);
		td.start();

		for (int j = 1; j < 100; j++) {
			System.out.println("Thread :" + j);
		}

	}

	class Runner1 implements Runnable {
		public void run() {
			for (int i = 0; i < 100; i++) {
				System.out.println("runner1:" + i);
			}
		}
	}

}

原因是：静态方法无法引用内部类。。。

netbean里没有任何问题啊

你现在的Runner1是内部类，把它变成外部类就好了
内部类隐式包含一个this引用指向包含它的外部类，但在main静态方法中，外部类TestThread还未实例化，当然this就找不到引用喽

可恶！！！！！！！！！！！！！
