Sir, actually printf inside if or while etc.. even works in C language. The main trick is printf returns a value which satisfies the if condition. Anyway this is an awesome trick Sir.

Just the kind of thing you could catch in a question in the OCA or OCP exams!

Hello Navin!!
What's the use by printing Hello World without Semicolon??

[charanguggulla]

sir, the following statement also prints without using semicolon

print here"));

of course, it prints reference of sout and I didn't use semicolon for inner sout.

If printf returns PrintStream then the condition == null must be false?

[parthtrehan]

hello sir.... the statement was working even without a semicolon...on netbeans 7.4

[shaileshsingh]

you know dude that was awesome, keep it up, i am watching your vids daily

[gopalbharadva]

amazing
i know new thing in my programing life

[shivrajpujari]

how did you entered inside that printf, what did u pressed to see details about printstream?

[sgcftw]

If we write printf instead of println then directly output is coming writing if condition, why

[shambhwishikha]

What ll happened if we use "println" Instead of printf;

[sunnyraj]

for example look at my program
class PrintWithoutSemicolon
{
public static void main(String[] args)
{int i=10;
if(System.out.printf("hello word")== null)
{

System.out.println(i);
}
else
{
int j;
j=++i;
System.out.println(j);
}}}
whats happning here is as sir said printf is returning printsteam(means the string the we provided) which is obviously not equal to null thats why condition failed and going to else statment an giving value 11.returning in the sence it's printing the string
hope it helped

[laljiprajapati]

if(System.out.append("Lalji prajapati\n").equals(null)){}

[jayaprakashveldanda]

i am unable to get the output in notepad i mean not in ides?

[mohangupta]

Hello
It works for me without this trick in mean to say i have written a code like this
package javaapplication3;

public class JavaApplication3
{


public static void main(String[] args)
{
System.out.println("Hello")
}

}
and this gives me no error in netbeans and gives the output.why? but gives the error in cmd as it is
and 1 more ques it necessary to use curly braces for if statement every time because it gives a error in cmd but nor in answer sir

[sushmasharma]

i wanna know netbeans ignore the error of ; or not????

[mouparnabag]

why void type method(println) cant be used with == operator? anyone help

[indappun]

why "sout" isn't working in eclipse?

[arjunkhanna]

Sir, what exactly is happening?
Explain in the detail & tell us about the theoretical part also... please

[TheYashwanth]

if condition returns false here because it doesn't return null. But, how does the statement present in the condition gets printed?
