I was wondering if in Java there was any way to give a new variable a name which is the value of another variable. The below code is an non working example of what I'm trying to do.
int a = 0;
while(true){
String (a) = "newValue";
a = a + 1;
}
or
String b = "newVariableName";
int (b) = 1;
Thank for any help given.
No this is not possible. It is possible to create a new object and add it to an array or some sort of list. Then you can reference the new object by the subscript. So a rough example could be:
Object[] a = new Object[30];
for(int i = 0; i < 30; i++)
{
a[i] = new Object();
}
and then you could use
a[some number].someFunction();
If you think about it, how can the compiler know what the value of a certain true variable is going to be, outside of the actual program run time? It is unlikely that you need to actually do what you want however.
You're trying to make an array or a list or a dictionary.
You cannot create dynamic variable names in Java. I would recommend placing these variables in a Map with a string as a key. The key can be whatever String you would like.
You can't do this. Use a Dictionary or a Map to store the values.
No, there's no way to do such a thing in Java. The closest you could do would be to create code at runtime and load a new class with fields made with dynamic names.
You might want to consider something simpler like a HashMap instance.
