• Static variables are shared among all instances of a class

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

• Static blocks are used to initialize static variables

• Static keyword can also be used to create nested classes

• Example: public static int count = 0;

Regression testing is testing the entire application after making changes, while retesting is testing only the failed test cases.

• Regression testing is done to ensure that the changes made to the application have not affected the existing functionality.

• Retesting is done to ensure that the defects found in the previous testing cycle have been fixed.

• Regression testing is time-consuming and requires a lot of resources.

• Rete...read more
