create a new local string variable from value of another variable?

Question

Is is possible to create an new local variable from value of another?

e.g. if value of var1 = "button1" can I construct a new local variable like button1type, ie.using the value of var1 to make part of the new variable

Where do you need this for? I think there will probably be a better solution for your problem. — Jordi

Depending on which button I press, I pass a value via extras and then using this need to make variable names to write to correct col in database. I can just use switch, case and have separate update database sql. Thanks anyway. — user1095784

Like this?

String foo = "ohai_" + var1; // Would be "ohai_button1"

If you mean name the variable based on the value in var1? No, but you don't need to.

If you need to associate data based on a string (or other) value, consider using a map.

@user1095784 I mean a map, HashMap is one implementation, and a typical choice.
