why we use static in java
In Java, static keyword is mainly used for memory management.
It can be used with variables, methods, blocks and nested classes.
It is a keyword which is used to share the same variable or method of a given
class. Basically, static is used for a constant variable or a method
that is same for every instance of a classstatic keyword in java
// example on static variable in java.
class EmployeeDetails
{
// instance variable
int empID;
String empName;
// static variable
static String company = "FlowerBrackets";
// EmployeeDetails constructor
EmployeeDetails(int ID, String name)
{
empID = ID;
empName = name;
}
void print()
{
System.out.println(empID + " " + empName + " " + company);
}
}
