Jump Statement in Java

Hello friends how are you, today in this blog i will teach you what is jump statement, types of Jump Statement , how Jump Statement works and many programs using Jump Statement in a very simple way. 

Let's start

• It is used to transfer the control from one point to another point in the program.
• There are three jump statements are used in java.
• break statement
• continue statement
• return statement

break statement

• It is used to transfer the control out of the body of loop.
• In other word we can say that it terminates the current loop.
• break statement are mostly used with loop(for,while,do while) and switch statement.

Example 1:Program without break

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=10;i++)
  {
  System.out.print(i+" ");
  }
 }
}
/*
### OUTPUT ###
1 2 3 4 5 6 7 8 9 10
*/

Example 2:Same Program with break

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=10;i++)
  {
  System.out.print(i+" ");
  if(i==5)//terminate the loop when i=5
   break;
  }
 }
}
/*
### OUTPUT ###
1 2 3 4 5
*/

continue statement

• It is used to skip the next statement and continue the loop.
• continue statement are mostly used with loop(for,while,do while).

Example 1:

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=5;i++)
  {
   if(i==3)//skip the next statement when i=3
    continue;
   else
    System.out.print(i+" ");
  }
 }
}
/*
### OUTPUT ###
1 2 4 5
*/

Example 2:

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=5;i++)
  {
   if(i>=3)//skip the next statement when i>=3
    continue;
   else
    System.out.print(i+" ");
  }
 }
}
/*
### OUTPUT ###
1 2 
*/

Example 3:

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=5;i++)
  {
   if(i<=3)//skip the next statement when i<=3
    continue;
   else
    System.out.print(i+" ");
  }
 }
}
/*
### OUTPUT ###
4 5
*/

Example 4:

class Easy
{  
 public static void main(String[] args) 
 {
  for(int i=1;i<=5;i++)
  {
   if(i!=3)//skip the next statement when i!=3
    continue;
   else
    System.out.print(i+" ");
  }
 }
}
/*
### OUTPUT ###
3
*/

return statement

• return statement terminates the current function and transfer the control to the calling function.
• we can also use return statement to transfer value from one function to another.

class Easy
{  
   int add()
   {
    int x=10,y=30;
    return (x+y);//returning x+y=40
   }
 public static void main(String[] args) 
 {
  Easy obj=new Easy();
  int rs=obj.add();//passing returning value to rs
  System.out.println("Add="+rs);
 }
}
/*
### OUTPUT ###
Add=40
*/
