Overloading a constructor or a method so it takes an extra argument based upon some specific requirement can result in duplicate code. For instance, a project that contains a lot of modules may have a requirement from a module to take to extra argument. To avoid this, pass "null" to the overloaded constructor:

Class Test {
	Test(String mgs){
		
		Test("data",null); // will call the Test(String mgs, Locale locale)
	}
	Test(String mgs, Locale locale){
		
	}

}
