Class A{
Public static synchronized void main(String args[]){

Sysout("hello");
}}

Java is case sensitive. 'Public' is not the same as 'public'. Please post the entire error you're asking for help with, copied from exactly as it appears at your end.

class A{
public static synchronized void main(String args[]){
Thread t= new Thread();
t.start();
System.out.println("hi");
t.wait(1000);
System.out.println("hello");
}}

o/p:
hi
Exception in thread "main" java.lang.IllegalMonitorStateException
at java.lang.Object.wait(Native method)


Works fine if we comment out wait statement
