Learn C programming, Data Structures tutorials, exercises, examples, programs, hacks, tips and tricks online. C program to check whether a character entered by user is vowel or not with output and explanation. Check Character is Vowel or not using Switch Case. C program to check vowel or consonant using switch c++ program to count number of vowels and consonants in a string write a program to determine whether the input character is a vowel or consonant. Java's switch statement is a multi-branching control flow statement. This tutorial explains switch, case, default and break statements of Java. Java's switch statement is a multi-branching control flow statement. This ch then passed to switch to check whether it is a vowel or consonant. Inside switch block default is placed first to. Program to check if input character is a vowel ot not using switch case in C language.
Unlike
if-then
and if-then-else
statements, the switch
statement can have a number of possible execution paths. A switch
works with the byte
, short
, char
, and int
primitive data types. It also works with enumerated types (discussed in Enum Types), the String
class, and a few special classes that wrap certain primitive types: Character
, Byte
, Short
, and Integer
(discussed in Numbers and Strings).The following code example,
SwitchDemo
, declares an int
named month
whose value represents a month. The code displays the name of the month, based on the value of month
, using the switch
statement.In this case,
August
is printed to standard output.The body of a
switch
statement is known as a switch block. A statement in the switch
block can be labeled with one or more case
or default
labels. The switch
statement evaluates its expression, then executes all statements that follow the matching case
label.You could also display the name of the month with
if-then-else
statements:Electronic circuit free download - Circuit Electronic Kits Design, Electronic Circuit Patterns, Electronic Circuit Design, and many more programs.

Deciding whether to use
if-then-else
statements or a switch
statement is based on readability and the expression that the statement is testing. An if-then-else
statement can test expressions based on ranges of values or conditions, whereas a switch
statement tests expressions based only on a single integer, enumerated value, or String
object.Another point of interest is the
break
statement. Each break
statement terminates the enclosing switch
statement. Control flow continues with the first statement following the switch
block. The break
statements are necessary because without them, statements in switch
blocks fall through: All statements after the matching case
label are executed in sequence, regardless of the expression of subsequent case
labels, until a break
statement is encountered. The program SwitchDemoFallThrough
shows statements in a switch
block that fall through. The program displays the month corresponding to the integer month
and the months that follow in the year:This is the output from the code:
Technically, the final
break
is not required because flow falls out of the switch
statement. Using a break
is recommended so that modifying the code is easier and less error prone. The default
section handles all values that are not explicitly handled by one of the case
sections.The following code example,
SwitchDemo2
, shows how a statement can have multiple case
labels. The code example calculates the number of days in a particular month:This is the output from the code:
Using Strings in switch Statements
In Java SE 7 and later, you can use a
String
object in the switch
statement's expression. The following code example, StringSwitchDemo
, displays the number of the month based on the value of the String
named month
:The output from this code is
8
.The
String
in the switch
expression is compared with the expressions associated with each case
label as if the String.equals
method were being used. In order for the StringSwitchDemo
example to accept any month regardless of case, month
is converted to lowercase (with the toLowerCase
method), and all the strings associated with the case
labels are in lowercase.Note: This example checks if the expression in the
switch
statement is null
. Ensure that the expression in any switch
statement is not null to prevent a NullPointerException
from being thrown.This is very simple Java program for implementing the switch statement.
This is very simple Java program for implementing the switch statement.This is very simple Java program for implementing the switch statement. Here, you will learn how to use the switch statement in your java program for developing java application. This section provides you the best illustration about some mathematical operations like Addition, Subtraction, Multiplication and division.
Program Overview And Result:
This section also provides you an example with complete java source code for understanding more about the switch statement in Java. The following java program tells you for entering numbers for involving in mathematical operations as your choice (whatever you want to do with both number). Four type of operations are listed through the program in sequence. Whatever you have to perform the operation firstly you have to enter you choice as an existing operation number for selecting operation what you want to do with entered two numbers.
Code Description:
Learn How To Program In Java
Here we are going to make a program to follows the switch statement. For completion the example firstly we define a class named 'SwitchExample' and two integer type values from users. Java I/O Package has a input Stream and a output Stream in which input stream is used for reading the stream and memory allocating . As in this program we are going to create a buffer for the string class that can be used to storing and processing a string character. Here in this program used the pursuing method for two integer value x and y. Now in this program use once again perform the parseInt method for Enter the choice number.
After that in this program we are going to use for the continue statement. This program take a number and check weather the number lies between 1 to 5. If the user enter the number 1 then the program print addition and enter the 2 then will be print subtraction so on up to 4 number otherwise when you user enter after 4 then will print 'Invalid Entry' massage using by the println() method.
Here is the code of this Example
import java.io.*; (new InputStreamReader(System.in)); |
