goto statement

[vijayapriya thirumurugan]

hello sir,

We use goto statement in c. is there any statement like this in java.

goto is a keyword in java which you cant use in code.i guess if you use goto, you will get compiler error

Try it and see

Hi,

There is no use of goto in Java. Instead of that you can use label in your code.

Thanks,
James

Sounds like your method has a logic error if you are trying to use GOTO.

Post your code.

Try using a combination of If Else, Switch, For loop and additional method calls to handle logic.

GOTO explained

public void process() {
  LOOPA
  for(int i = 0; i < counter; i++) {
    // do something
    if(valid) {
    helperMethod(i);
    break LOOPA;
    }
}

public void helperMethod(intvalue) {
   //do something else
   switch(value) {
   case 0: //something;
              break;
   }
}

Here is an old thread that discusses the "goto" in Java.

Eric Mission, agree. As far as I am concerned, even thinking about "goto" is a logic error.

In fact you can always use a combination of selection repetition and sequence to implement absolutely everything; even your labelled "break" is unnecessary. By the way: it#s not LOOPA but LOOPA:

Ah! yes it is- Some days I wish forums had compilers built into them so banging out small examples like that could be syntax checked Alas, I would also like to win the lottery...

So very true, though I figured that if someone was posting a question about a GOTO statement in OOP I thought that by presenting the most basic of basic programming methods I could think of may shine some light for him/her, though probably a mute attempt. Not to mention providing an example of using a label as James suggested.

Just at the moment we are having difficulty with delays for ordinary text, so no chance of a free compiler

Wonder why did they reserve the Goto keyword

[Henry Wong]

We use goto statement in c.

I have to challenge this... no C programmer worth his salt should be using the goto statement. I used C for many years, including device drivers, network drivers, kernal code, etc. And I have never used goto... Well, except once, due to time constraints, and I went back and got rid of it. If it was Java, I would have been forced to do it correctly the first time.

I read somewhere that the goto keyword was retained so compilers could throw better error messages. Can't remember where. Sorry.
