How to connect your program to another program? And how many program can be connected?

.well i want to call another program, e.g Theres a 3 buttons "red, blue, green" : when i click red, its going to call a program to add the numbers. when i click green, its going to call another program to subtract. and when i click blue, its going to call another program to divide. So there are 4 programs to connect. The RED, BLuE, Green and the Main program. ^^

I'm not sure what you mean by "connect". If you are asking about one class having a reference to another class that it can use to call methods in the other class, there are no limits to the number of references to other classes that a class can have.

Use the new statement to create instances of a class.

OtherClass oCls = new OtherClass();  //  create an instance of OtherClass
 
oCls.someMethod(); //  call method in OtherClass
