What is OutOfMemeryError injava?how to deal with java lang.OutOfMemeryError error?

Question

I have used below code,

textareaA.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable arg0) {
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
    }

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        double val = Double.parseDouble(textareaA.getText().toString());
        textareaB.setText(String.valueOf(val/10000));
    }      
});

textareaB.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable arg0) {
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
    }

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        double val = Double.parseDouble(textareaB.getText().toString());
       textareaA.setText(String.valueOf(val*10000));
    }      
});

If I type a value in any EditTexts, it crashes and trows java.lang.StackOverflowError error.
Suggest a solution.

Answer 1

you always have a finite max of heap to use no matter what platform you are running on and same with java happens.Recently I got this error while drawing bitmap in android studio just because it was increasing the allotted heap memory.I changed the dimensions and after that error was solved.
Try to run your programs with -Xmsn to give maximum heap memory to your program.
Example:

->   -Xmx50m

to allocate 50MB memory.
