How to check if String value is Boolean type in Java?

I did a little search on this but couldn't find anything useful.

The point being that if String value is either "true" or "false" the return value should be true. In every other value it should be false.

I tried these:

String value = "false";
System.out.println("test1: " + Boolean.parseBoolean(value));
System.out.println("test2: " + Boolean.valueOf(value));
System.out.println("test3: " + Boolean.getBoolean(value));

All functions returned false :(

  function isBooleanString(val) {
    if (val === "true" || val === "false"){
      return true
    } else {
      return false
    }
  }
isBooleanString("true") // true
isBooleanString("false") // true

isBooleanString("blabla") // false
