[PDF] a static method can use local variables

In Java, a static variable is a class variable (for whole class). So if we have static local variable (a variable with scope limited to function), it violates the purpose of static. Hence compiler does not allow static local variable.

  • Can static methods use static variables?

    Static methods only have access to other static variables and static methods. Static methods cannot access or change the values of instance variables or the this reference (since there is no calling object for them), and static methods cannot call non-static methods.

  • Is local variable static or non-static?

    The Local variables and Instance variables are together called Non-Static variables.

  • Can static methods use private variables?

    Private member variables of class A can be accessed (i.e. read/written to) by any method of class A (static or non-static), so in your example, since the method changing the string is a method of the same class the member belongs to, it is granted access to the variable.
  • A variable cannot be local and static at same time. Local variable means variable which is defined as part of code block or method and its scope is within that code block or method. This variable can't be accessed outside its boundary.
