In C#, Jump statements are used to transfer control from one point to another point in the program due to some specified code while executing the program. There are five keywords in the Jump Statements:
- break
- continue
- goto
- return
- throw
break statement
The Break statement is used to terminate the loop or statement it is in. Control is then passed to the statement following the break statement, if available. If a Break statement is present within a nested loop, only the loop containing the break statement is terminated.
Example:
// C# program to illustrate the
// use of break statement
usingSystem;
class CodeConfigs
{
// Main Method
staticpublicvoidMain()
{
// CodeConfig.in is printed only 2 times
// because of break statement
for(inti = 1; i < 4; i++)
{
if(i == 3)
break;
Console.WriteLine("CodeConfig.in");
}
}}
Output: CodeConfig.in CodeConfig.in
continue statement
This statement is used to skip the execution part of a loop under certain conditions. Control is then passed to the beginning of the loop. Basically, the next statement is skipped and you move on to the next iteration of the loop.
Example:
// C# program to illustrate the
// use of continue statement
usingSystem;
class CodeConfig
{
// Main Method public static void Main()
{
// This will skip 4 to print
for(inti = 1; i <= 10; i++) {
// if the value of i becomes 4 then
// it will skip 4 and send the
// transfer to the for loop and
// continue with 5
if(i == 4)
continue;
Console.WriteLine(i);
}
}}
Output:1 2 3 5 6 7 8 9 10
goto statement
This statement is used to transfer control to the labeled statement in the program. The label is the valid identifier and placed just before the statement from where the control is transferred.
Example:
// Below is C# program to illustrate the
// use of goto statement
using System;
class CodeConfigs
{
// Main Method
static public void Main()
{
int number = 20;
switch (number) {
case 5:
Console.WriteLine("case 5");
break;
case 10:
Console.WriteLine("case 10");
break;
case 20:
Console.WriteLine("case 20");
// goto statement transfer
// the control to case 5
goto case 5;
default:
Console.WriteLine("No match found");
}
}
}Output: case 20 case 5
return statement
This statement terminates the execution of the method and returns the control to the calling method. It returns an optional value. If the type of method is void, then the return statement can be excluded.
Example:
// Below is C# program to illustrate the
// use of return statement
using System;
class CodeConfigs{
// creating simple addition function
static int Addition(int a)
{
// add two value and
// return the result of addition
int add = a + a;
// using return statement
return add;
}
// Main Method
static public void Main()
{
int number = 2;
// calling addition function
int result = Addition(number);
Console.WriteLine("The addition is {0}", result);
}
}Output: The addition is 4
throw statement
This is used to create an object of any valid exception class with the help of new keyword manually. The valid exception must be derived from the Exception class.
Example:
/ C# Program to illustrate the use
// of throw keyword
using System;
class CodeConfigs{
// taking null in the string
static string sub = null;
// method to display subject name
static void displaysubject(string sub1)
{
if (sub1 == null)
throw new NullReferenceException("Exception Message");
}
// Main Method
static void Main(string[] args)
{
// using try catch block to
// handle the Exception
try
{
// calling the static method
displaysubject(sub);
}
catch(Exception exp)
{
Console.WriteLine(exp.Message );
}
}
}Output: Exception Message
