Well, I don't get your question.
The point of using if is to do one job or the other based on some condition.
If you want to do both the jobs, then you dont need to use if itself.

Perhaps if you provide some sample code and say where you face problems, we can be able to help..

ya goyal is right.
but if it is a tricky question(we have to solve it by anyway).
then i think that this is the method by which we have to do this.

import java.io.*;
class m
{
public static void main(String arg[])
{
boolean x;
if(x=true)
{
System.out.println("mohit ");
x=false;
continue;
}
else
{
System.out.println("cboy hack the world");
}
}
}
but here what keyword is placed in the place of continue so that it will execute the if statement again.

exactly!
there's no point using an IF ELSE statement if both have to be typed. Even if it is a trick question, it is a foolish one 'cos one will never need an IF ELSE statement if both the things have to be worked out.

public class demoif {

public static void main(String[] args) throws Exception {
if ( System.out.printf("Hello") == null ) {

}
else {
System.out.println("World");
}
}
}
it is the perfect ans u can try

Hey neha,if you want get the output as hello world, then try without else,then you definitely going to get the out put..But you can't get the both if and else part...
other wise if you want to get those output fallow this code(using labels)...
int a=1;
l1:if(a==1)
{
System.out.println("hello");
a=0;
}
else
System.out.println("world");
goto l1;

this is work in c and c++,, But i'm not sure in java.. Just try...

yup , silverscorpion is right it goes fr infinite loop.

i believe that we use " if else "only in case we want to solve cases of either or still if u solely aim only to print " hello world "
then try like

import java.io.*;
class trial
{
public static void main(String args[])
{
boolean x;
int c=0;
while (c<2)
{
if(x=true)
{
System.out.println("hello" );
x=false;
}
else
System.out.println("world" );
c=c + 1;
}
}
but its like getting something purposefully.
help me if i m wrong.

l1:if(a==1)
