Yes, a Java program can contain more than one “main” method in a class. You can say by passing different arguments in the same main() method. This is called as overloading the main method.
Similarly another method which is Method2() is being defined with ‘public’ access specifier and ‘void’ as return type and inside that Method2() the Method1() is called. Hence, this program shows that a method can be called within another method as both of them belong to the same class.
Subsequently, Is it possible to call a class method from another class method?
Use the method call syntax to call a class method from another class. Instantiating a class and assigning it to a variable is the same as using a different class to call its methods.
Also, Which are also known as inner classes?
Non-Static Nested Class (Inner Class) A non-static nested class is a class within another class. It has access to members of the enclosing class (outer class). It is commonly known as inner class .

How do you call a method with parameters from another method in Java?
A method that accepts parameters must list the parameters in the method declaration. The parameters are placed in a parameter list inside the parentheses that follow the method name. For each parameter used by the method, you list the parameter type followed by the parameter name.
Can an application have multiple classes having main method?
We can have different classes having the main methods. … Yes you can have more classes that contain public static void main(String[] args) . And you can chose to execute one class or another class. However, you can’t have more than one main method within same class.
Can you call a method within a method?
Java does not support “directly” nested methods. Many functional programming languages support method within method. But you can achieve nested method functionality in Java 7 or older version by define local classes, class within method so this does compile.
Are methods always part of a class?
It is not possible to have methods without them belong to a class. You have listed the two kinds: static which belong to the class instance (only one) and non-static which belongs to the individual object (one pr new).
Can we call main method inside main method?
Solution: Though Java doesn’t prefer main() method called from somewhere else in the program, it does not prohibit one from doing it as well. So, in fact, we can call the main() method whenever and wherever we need to.
What are different types of classes?
– Abstract class.
– Concrete class.
– Sealed class.
– Static class.
– Instance class.
– Partial class.
– Inner/Nested class.
What is the difference between a class and a method?
The main difference between Class and Method is that Class is a blueprint or a template to create objects while a method is a function that describes the behavior of an object.
Can main be called inside main?
Yes, we can call the main() within the main() function. The process of calling a function by the function itself is known as Recursion. Well,you can call a main() within the main() function ,but you should have a condition that does not call the main() function to terminate the program.
What is class example?
Definition: A class is a blueprint that defines the variables and the methods common to all objects of a certain kind. The class for our bicycle example would declare the instance variables necessary to contain the current gear, the current cadence, and so on, for each bicycle object.
Can you use a method inside another method?
Java does not support “directly” nested methods. Many functional programming languages support method within method. But you can achieve nested method functionality in Java 7 or older version by define local classes, class within method so this does compile.
What is class and its types?
Classes are reference types that hold the object created dynamically in a heap. All classes have a base type of System. Object. The default access modifier of a class is Internal. The default access modifier of methods and variables is Private.
Do all Java classes need a main method?
Yes, it is required for any executable program. If you try to execute a Java class, the JVM will look for a main method to invoke it. … Not all classes need a main , only the one that serve as “entry point” for execution.
Can main be called inside printf?
2 Answers. Yes. Although it’s rather special in some ways, printf is just another function. And a function call can be part of an expression.
Can you create classes in Python?
A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class .
