Java – Control statements


Java Control statements :

  • The Java control statements inside a program are usually executed sequentially. Sometimes a programmer wants to break the normal flow and jump to another statement or execute a set of statements repeatedly.
  • Control statements in java which breaks the normal sequential flow of the program are called control statements.
  • Control statements in java enables decision making, looping and branching.

Decision making statements:

These statements decides the flow of the execution based on some conditions.

  • If then
  • If then else
  • switch

Loops Control statement:

  • Loop control statements change execution from its normal sequence.
  • When execution leaves a scope, all automatic objects that were created in that scope are destroyed.

Statements inside a loop are executed repeatedly provided with some condition which terminates the loop.

  • for – For loop executes a set of statements repeatedly until a specified condition evaluates to false.
  • while & do while – Do while loop is similar to that of the while loop except that the condition is evaluated at the end of the loop in do-while whereas in while loop, it is evaluated before entering into the loop.

Branching statements:

Branching statements are used to jump from the current executing loop.

  • break – Terminates the loop or switch statement and transfers execution to the statement immediately following the loop or switch.

Example For Break statement :

  • continue – Causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.

Example for Continue statement:
