Thread: Calculator in eclipse

i need help for the code of the memory buttons(M+, M-, Mr and Mc). someone help me pleasee

Show us your code, and we'll help if we can. And why do you need help with the memory buttons. Memory is a variable. You add to the variable, subtract from the variable, get the value of the variable, or set the value of the variable to zero. Pretty darned simple.

That you're using Eclipse as your IDE is irrelevant. That you're programming in Java is all that matters.

JButton btn_Mm = new JButton("M-");
btn_Mm.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
here i have 2 write what ???

}

here i have 2 write what ???

calculator.subtractFromMemory( calculator.getUserInput() );

Of course I've made up names for variables and methods, but the gist of it is that the code in that action listener subtracts the user's input from an existing variable in which the current value of the calculator's memory is stored.

eemm... can you help me with a tutorial

No, though there are several calculator tutorials on the Internet. If you've written the rest of the calculator or developed the code you have from other tutorials, this part is trivial, IF you understand what you've done so far. If you don't, I can't help you.

yes i know what i have done, but im having problems with the memory button,,, i have problems with the language and i cant explain you well the problem, whatever... thanks for the reply!
