Thread Synchronization (2)

In thread synchronization when a method is marked as synchronize, other threads are not accessible at the same time, but other methods and properties can be accessed, and data can be changed.

Instance:

Package com.exmaple.Thread;

public class Test6 implements runnable{

/**
* When a method is marked as synchronize in thread synchronization, other threads cannot be accessed concurrently
* But you can access other methods and properties, and you can change the data.
* @param args
*/
static thread thread;
private static number num;
public static void Main (string[] args) {
TODO auto-generated Method Stub
Num=new number ();
Test6 t=new Test6 ();
Thread t1=new thread (t);
T1.start ();

try {
Thread.Sleep (1000);
} catch (Interruptedexception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}

Num.f2 ();
}
@Override
public void Run () {
TODO auto-generated Method Stub
NUM.F1 ();
}

}
Class Number {
int i=10;
Public synchronized void F1 () {
i=100;
try {
Thread. Sleep (5000);
} catch (Exception e) {
Todo:handle exception
}
System.out.println ("i=" +i);
}
public void F2 () {

try {
Thread. Sleep (2000);
} catch (Exception e) {
Todo:handle exception
}
i=200;
}
}

Description: In the main thread from the creation of a child thread, the child thread executes, i=100, enters sleep, and the method is locked. Meanwhile, the main thread executes the following code F2 (), I is changed i=200;, Child thread sleep wake, output
