Jump statement in Java programming Hands on Coding

Jump Statement in Java ?

Jump statement in Java;

It can be used to transfer the control from one point to other point in the program.
There are mainly three jump statements in java.

break statement
continue statement
return statement

break statement;

It can be used to transfer the control out of the body of loop.
In other words we can say that it terminates the current/present loop.
break statement are mostly used with loops such as (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 /
