What is a method, void, static?

every method has a return type depends upon what type of method we created example

public int method name{ int val=5; return val (this method will return integer variable or value ) }

every method has a return type

void means it will return nothing.

static static variable static method

static means if we want to use static variable or static method we don't need to create a object of that class we can directly use that function.

example

we mostle use math.random(); function

math is a class and random() is a static method because we are directly usin random() function with class name

we never created the obect of math class.

For a bit more clarity... Methods are used in object orientated programming to actually do something in code. Whenever you do anything in Java, you are using a method.

A method will always return something, unless it is declared as void, like in the below example. It's changing the value of the variable gear to the provided argument newValue. It's not returning something, but Java will throw an error, cause if void isn't declared, then it'll expect a return statement near the end of the code block.

public void setGear(int newValue) { gear = newValue; }

In contrast, in the below example, we're asking Java to return an int value.

public int getArea() { return width * height; }

Finally, static means that the method is associated with the class, not a specific instance of that class. Basically, it means you can call a static method without having to create an object of the class.
