public class ThreadSynch2 {
public static void main(
String[] args) {
Synchr s = new Synchr();
s.setName("one");
s.start();
Synchr s1 = new Synchr();
s1.setName("two");
s1.start();
}
}
The ooutput of the above program is
method1-------0 one
method1-------0 two
method1-------1 one
method1-------1 two
method1-------2 one
method1-------2 two
method1-------3 one
method1-------3 two
method1-------4 one
method1-------4 two
method2-------0 one
method2-------0 two
method2-------1 one
method2-------1 two
method2-------2 one
method2-------2 two
method2-------3 one
method2-------3 two
method2-------4 one
method2-------4 two
I could not understand why thread 2 is called before one completes even though the method is synchronized.
Sorry if there was any mistake in this
Please clarify me
