You must understand why we need methods, what they are used for, and how we will benefit from them by creating Java programmes before you can create static-void types, static methods returning anything other than void, or any other kind of methods.
These are the steps to check while developing Methods:
✔ Methods defines a particular functionality or behaviour using the
properties of a class.
✔ Methods needs a suitable definition block.
✔ Methods needs a suitable definition block.
✔ By invoking a developed method, we are getting reusability from methods
again and again.
again and again.
✔ The entry and exit points for Java command invocation are found in the
main method.

✔ If a methods is returning something other than void type, it is required to
keep corresponding return type; otherwise, you will get compile-time
error.

✔ Local variables can't be used in other methods, since it is local to a
perticular method.

If the class is called MyClass, the constructor should be called Only

✔ There is no return type for constructor.
✔ When an object is formed, a Constructor is automatically loaded, and
A constructor is required for each object creation statement.
✔ At least one constructor is required for each class, and if you don't keep
any constructors, the compiler will provide them for you default
constructor with no arguments.
✔ We can't create an object without a constructor, and for one constructor
N objects are kept/created.
