What is the difference between void and non void methods in Java?

What is the difference between void and non void methods in Java?

The way that a non-void method is called differs from the way that a void method is called in that the call is made from within other Java statements. Since a non-void method always returns a value, this value has to be stored in a variable, printed, or returned to a Java control structure or another method.

Can we use void and return together?

A void() cannot return a value that can be used. But it can return a value which is void without giving an error.

Can you call a void method in Java?

The void keyword allows us to create methods which do not return a value. This method is a void method, which does not return any value. Call to a void method must be a statement i.e. methodRankPoints(255.7);. It is a Java statement which ends with a semicolon as shown in the following example.

What is the opposite of void in Java?

static means that the method is associated with the class, not a specific instance (object) of that class. This means that you can call a static method without creating an object of the class. void means that the method has no return value. If the method returned an int you would write int instead of void .

Can a void method have a return statement Java?

Any method declared void doesn’t return a value. It does not need to contain a return statement, but it may do so. The data type of the return value must match the method’s declared return type; you can’t return an integer value from a method declared to return a boolean.

What does public void class1() do in Java?

public void class1 () is not a constructor, it is a void method whose name happens to match the class name. It is never called. Instead java creates a default constructor (since you have not created one), which does nothing.

Why is the constructor of a void void in Java not called?

It is never called. Instead java creates a default constructor (since you have not created one), which does nothing. Using void in the constructor by definition leads it to not longer be the constructor. The constructor specifically has no return type.
