Internal Details of Java
We are going to learn, what happens while compiling and running the java program. Moreover, we will see some question based on the program. What happ
Bitwise and Bit Shift Operators
The Java programming language also provides operators that perform bitwise and bit shift operations on integral types. The operators discussed in this section are less commonly used.
Equality, Relational, and Conditional Operators
The equality and relational operators determine if one operand is greater than, less than, equal to, or not equal to another operand. The majority of these operators will probably look familiar to you as well.

Interface E.g.
interface Car { // wheel revolutions per minute void changeCadence(int newValue); void changeGear(int newValue); void spee
