How to declare an array of different data types [closed]

Answer 1

Creating an Object[] array is one way to do it. Otherwise, you can create a class with the variables you want, and have an array of that class's objects.

class MyClass{
    int var_1;
    String var_2;
    ...
    ...
}
...
MyClass[] arr = new MyClass[3];

Then, use arr where you want to.
