Static keyword in Java is used to create class-level variables and methods.

• Static variables and methods belong to the class rather than the instance of the class.

• Static variables are initialized only once at the start of the program.

• Static methods can be called without creating an instance of the class.

• Static keyword can also be used to create static blocks that are executed only once when the class is loaded.

• Example: Math.PI is a static variable in the Math class.

• Example: Th...read more
