Condition String Resolver in java API? [closed]

Answer 1

As of java 1.6 you can use the ScriptEngine and evaluate javascript if this is enough for you and/or if you don't want to introduce another library.

ScriptEngine scriptEngine = new ScriptEngineManager().getEngineByName("javascript");
SimpleBindings bindings = new SimpleBindings();

bindings.put("a", 0);
bindings.put("b", 6);

boolean firstEval =  (Boolean) scriptEngine.eval("a != 0 && b > 5", bindings);
System.out.println(firstEval);

bindings.put("a", 2);
bindings.put("b", 6);

boolean secondEval =  (Boolean) scriptEngine.eval("a != 0 && b > 5", bindings);
System.out.println(secondEval);

Output

false
true
