It evaluates two statements/conditions and returns true only when both statements/conditions are true. Static loading: A block of code would be loaded into the RAM before it executed ( i.e after being loaded into the RAM it may or may not get executed ). C++ breaks the concept of encapsulation because the main ( ) method in a C++ program is declared outside a class. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In this program, we will see how to perform logical operations in java when the values are pre-defined. You may also find these Java programming questions in most Java courses taught in schools, colleges . Every function will have access to all the global variables.

Intermediate level (2-7 years) experienced. For example, + is an operator used for addition, while * is also an operator used for multiplication. The Logical programs are designed by using certain logic and can say 70 percent code of the program is a set of logic. Logical NOT is a Unary Operator, it operates on single operands. If the new programmer adds a new function to the existing code in the way of upgrading it, there is no guarantee that it will not affect the existing functions in the code.
