JAVA Theory Part-5

DEFINITIONS(Part-5)

Increment Operator: Increment operator increases the value of operand by one.

Decrement Operator: Decrement operator decreases the value of operand by one.

Erythematic Operator: An Operator which performs arithmetic functions is known as Erythematic Operator.

Logical Operator: These Operator yield results in 0 and 1 depending upon the outcome of the result. They check between two variables or values.

Relational Operators: Operators which are used to show or check relationship between operands are known as relational operators.

Precedence of operators: Specific order in which the operators in an expression are evaluated when the expression has several.

Bitwise Operator: The Bitwise operators calculate each bit of their result by comparing the corresponding bits of the two operands. (a) The AND operator & (b) The OR operator |(c) The XOR operator ^ (d) The compliment operator ~.

Compound Statement: It is a block of code containing more than one executable statement. In Java the { } is called block and the statements written under {} is called compound statements or block statement. The { } opening and closing braces indicates the start and end of a compound statement.

Mathematical Functions: The methods which perform mathematical calculations and which are included in a package of java. This package is automatically imported into the class.

Return Type: It is the data type used before the method name in the method header that indicates the type of the outcome value.

Return value: It is the value that returned to the caller when the function is invoked.

Variables: A variable is a stored memory location .It is used to store different constant values.

Label: Default and case keywords are known as labels.

Fall through: The unusual execution of more than one cases at a time is known as fall through. This occurs when the case is not applied between two or more cases. The control executes to the next case also for execution.

Statement Terminator: Semicolon is the statement terminator in Java. It indicates the end of a statement.

Case Terminator:  Break keyword is used as case terminator. Break does not allow the control to execute on to the next case. It indicates the end of the case.

Jump statement: Break and Continue are the two jumping statements. Break terminates the execution of the loop or program. Continue skips the execution of one iteration of a loop.

Testing: Testing is the process in which the program is validated by checking all the specifications desired.

Debugging: Removal of errors in the program is known as Debugging.

Iteration: Process of repeating mathematical or computing process or set of instructions again and again each time applying it to the previous stage is called Iteration.

Loop: Set of instructions that are repeated again and again until a particular condition is satisfied.

Control Variable: A variable, which starts with an initial value and determines the duration of repetition is known as Control variable.
