not able to execute the method based on OS in JAVA

[smartgupta]

HI,

I want to use same methods specific to OS but when I am trying to do so,I am only able to find out the OS name but it is not going inside that.I wrote a simple code as below --

public class OSnane {

public static void main(String[] args) {

String OsName=null;
OsName=System.getProperty("os.name");

System.out.println("OS name="+OsName);
if(OsName == "SunOS")
System.out.println("hello Sun");
else if(OsName == "Windows XP")
System.out.println("Hello Windows");
else if(OsName == "Linux")
System.out.println("Hello Linux");
else
System.out.println("No OS selected!!!");


}

}

and Output is

OS name=SunOS
No OS selected!!!

So how can I use the method based on the OS..

Thanks in advance....

if(OsName == "SunOS") // == doesn't work with string

try this:
if(OsName.equals("SunOS"))
