Converting a string into a boolean condition

Question

Say I have a String

String strCondition = something.contains("value") && somethingElse.equals("one");

How do I convert this String into a boolean condition so that I can be able to use it in an IF statement?

If I use valueOf(), will it evaluate the contents of the String?

RE-EDIT: I am not sure how to put this.

I am taking the value something.contains("value") && somethingElse.equals("one") from a database column. If I try to assign that to boolean variable it shows a type mismatch.

Answer 1

you don't.

it already is a boolean expression.

something.contains("value") -> this returns either true or false && somethingElse.equals("one"); -> this also returns true or false.

what you need, is either:

boolean strCondition = something.contains("value") && somethingElse.equals("one");
if ( strCondition )

or

if ( something.contains("value") && somethingElse.equals("one"))

EDIT:

The above would either return true, false, or throw a nasty NullPointerException.

To avoid the latter, you should use:

if ( "one".equals(somethingElse) && (something != null && something.contains("value"))
