Is it Mandatory to declare Methods with a Return Type in Method Declaration in Java?

In Java it is mandatory to declare Methods with a return type in a method declaration!

The data type of the return value in a method must correspond to the method declared return type if not ‘void‘. The return types for methods must be of primitive type, that is, it has to be pre-defined and named as a reserved key word in Java, e.g., int, float, void, etc.

For instance, if we declare a Method “mathsMethod()” with a Type “int“, its Return Type must also be “int“.

returnType methodName() {
  // body of the namedmethod
}

methodName()

int mathsMethod(){
  System.out.println("Method Return Type must be declared!")
}

mathsMethod()
