Java-尝试暂停线程[重复]

Question

可能重复:
Java等待并通知：IllegalMonitorStateException

有什么问题

    private final Object lock; 
public synchronized void run() {
    while (numItersCompleted < maxNumIters) {
        while (guiState == GuiState.PAUSED) {
            try {
                lock.wait(); // problematic line

投掷：

java.lang.IllegalMonitorStateException
at java.lang.Object.wait(Native Method)
at java.lang.Object.wait(Object.java:502)

Answer 1

您没有围绕锁synchronized。

public void run() {
    while (numItersCompleted < maxNumIters) {
        while (guiState == GuiState.PAUSED) {
            try {
                synchronized (lock) {
                    lock.wait(); // problematic line
                }
