Quit cluttering the forum with 3 postings on the same topic.

Use the "Code" tags when posting code to the code is readable. You can Edit your posting and replace the code.

[rithish]

iam new sir please what is "code" tag????

[camickr]

Find the appropriate button (icon) in the editor window. Its just like using the "Bold" or "Italic" button.

[rithish]

now i understood sir

[rithish]

sir help me

[RichersooN]

You coding of your program is really bad why?
#1 The name of the variable is the same as in outside, like your textfields
#2 You make the textfield as an object(Whats the point? )

I THINK IT'S BETTER IF:
.
.
//transfer all the information from class1 to class2
.
.
class2.setVisible(true);

[rithish]

ok sir what s the lead sir now where should i correct

[RichersooN]

You should use getters and setters to transfer all the data from class1 to class2

if you don't know how to do it, you should learn the fundamentals ^_^ you're not ready for intermediate topics yet

[rithish]

ok if i make class1 object.setvisible(true);.will it make correct

[RichersooN]

WHAT IS that OBJECT?
Cant it be like this?:

class1{
.
.
.
         class2.setVisible(true);
.
.
.
}

I THINK WITH YOUR CODE IT WILL ONLY MAKE THE class2 appear but no data from class1

[rithish]

thank u very much sir

[rithish]

ok if i use a get method should i use a return value
