break statement

[shana07]

Good Day all!...Could I ask one question about break please...
Why I am getting nothing when I put this break? at least it prints something
if it's true...please refer my codes below:

if(name2.equals(name1)) {
       if(add2.equals(add1))  {
          if(!(val2.equals(val1)))              {                                                                                                 
   printWriter.println(fileno + " : " + name2 );
    break;
                     }                    
                } 
                 
           }

It works fine if I take out the break statement. But then it will exercise all lines in my inputfile. What I want is, after I got the first output then it will stop checking the next line....please feel free to reply me. thank you.

Post code for the whole loop that you are trying to break from.

[JosAH]

break statements can only occur in loop bodies where it stops the loop immediately
or in case clauses in which case the break prevents "fall-through" and breaks
out of the entire switch statement. Your code snippet doesn't show loops nor
switch statements ...

Thank you very much..Now I know about the break..I thought it can stop from execute/read next line (FileReader) by putting the 'break' statement.
so there's no way to put break after 'if' syntax..

One more question about readLine() please...
How am I going to get the last line (EOF)- value to be printed?
I have this code:

line1 = in1.readLine();
line2 = in2.readLine();

while ((line1 ! = null) && (line2 != null)) {
 ............ 
....
line1 = in1.readLine();
line2 = in2.readLine();
}

//then I need to print out the last line for both files?

Kindly please help me what's the syntax for printing the lastline value?
Thank you

try this code ......

while((line1 = in1.readLine()) != null && (line2 = in2.readLine()) != null)
{
//prints two strings here.
}

if(line1 != null)
{
//prints the line1
while((line1 = in1.readLine()) != null) //prints the line1
}
else if(line2 != null) //prints the line2
{
//prints the line2
while((line2 = in2.readLine()) != null) //prints the line2
}

i think u got my logic.
have a good day.

sorry friend, I don't really get you...anyway I have tried to follow your code - but it doesn't print the last line value still...thank you.

 String lastLine = ""; 
while(line != null) {
 
line = input.readLine();
if(line != null) { 
	 lastLine = line;
}
}
 
System.out.println(lastLine);

hello shana07

did u understand my // line??????

do one more thing if u can plz post ur code what u write with the help of me....

[AdrianH]

My 2 cents: Don't use break/continue to manover your way around loops. Bad form old boy.

Unless you have some profiling proof that says that you should use it, don't. It makes for harder to read and verify the code.

good idea suggested by AdrianH.

if there is no way then u should use it ... otherwise not.
