| Java Programmers - How Do I Pass Variable Value From A Classa To Another Classb by ERCROSS(m): 9:39am On Mar 21, 2018 |
The program has three classes. The main thread class(let's call it class0), The second class collects input from users (Let's call it classA) The third class (Let's call it classB) is meant to use the value input from classA in some of its program. When I made classB extend classA, and I was able to use that particular classA variable within the classB. But I want to know if there is another way I can make that classA variable be used in the classB |

Create a fourth class and lets call that class classFour. Set up classFour in a way its fields can hold each of the variables you got from classA within classB From within classB instantiate a new classC and pass the inputs you got from classA to classC like this ; ClassFour cf = new ClassFour(); cf.setField1 = input1; cf.setField2 = input2; . . . And so on. Then set classFour as a field within ClassC (cc) in our case. ClassC cc = new ClassC(); cc.setCf(cf); note: i had to type this on a opera mini 240 x 320 screen. It may not be neat on your side. 2 Likes |

Call the object of the class u want to use it variable and use dot notation to call the variable in the class u wish to use it. Note(make sure the variable is not declare private in the first class, if it is create a getter and setter method for each variable) 1 Like |

Guys, I've gotten a solution to the problem. What I did was that I went to the main thread, called the classC methods that are meant to convert the digit input to word. I ensure that these methods within classC has parameters type int (since the methods will be working an integer input) so that when I invoke them from the main class, I can pass them the value of the digit input as an argument. The identifier I used as the argument has been declared as an instance variable of the main thread, so the initialization occurred when I passed it the value of the digit input.. |
