block of code......
catch{
exception 1.....
}

catch{
exception n.....
}
finally
{
System.out.print(" I am a finally block");
System.out.print(" I always executed exception handled or not");
}
}

Program

public class try_keyword{
    public static void main(String args[]){
        try{//try block for exception handling

    }
    }
