Types of Control Statement in java
Posted by Gyan Guide on May 12th, 2017
A program executes from starting to ending except when we use control statements.Through control statement we control the order of execution of the program, on the basis of some logic and values.
In Java, We can divide the control statements into the following three categories:
1) Selection Statements
2) Iteration Statements
3) Jump Statements
Selection Statements :
- if statements
- if-else statements
- if-else-if statements
- switch statements
The if statements :
if statement only executes when the specified condition is true. If the condition is false and there is not else keyword then the if statement will be skipped and execution continues with the rest of the program. The condition is an expression that returns a boolean value.
The if-else statements:
The if-else-if statements:
The Switch Statements
The switch statement is a multi-way branch statement . Advanced java training in bangalore The switch statement of Java is defines multiple paths of execution of a program. It provides a good alternative than a large series of if-else-if statements.
Repeating the same code partmultiple times until a specified condition is satisfied is called iteration. Iteration statements execute the same set of instructions until a termination condition is met.
1) for loop
2) while loop
3) do-while loop
4) for each loop
The for loop :
The while loop :
It executes a block of statements while a condition is true. The condition must return a boolean value. In while loop initial condition is unknown.
The do-while loop :
The only difference between a while and a do-while loop is that in do-while loop first executes the statements then check the condition . If the condition is false then also execute the statement once.
In while loop first check the condition then execute the block of statement.if condition false then never execute the block.Best core java training in bangalore
Labeled Break Statement: This is used for when we want to jump the program control out of nested loops or multiple loops.
Unlabeled Break Statement: This is used to jump program control out of the specific loop on the specific condition.
Continue Statement :
The continue statement is used when we want to continue running the loop with the next iteration and want to skip the rest of the statements of the body for the current iteration.
1) Labeled Continue Statement
2) Unlabeled Continue Statement
