increment operators

[Angela lewis]

  public class TestClass
{
   public static void main (String args[ ] )
   {
      int k = 1;
      int i = ++k + k++ + + k ;  //1
      System.out.print(i+ " "+ k) ;
   }
}
 

I fail to understand the 2 + signs before k in 1.

You can very well remove one of the +.. It is there to confuse us.. and simply means that k is positive.

You can change it to the following to see the difference

  
                int k = 1;
int i = ++k + k++ + -k ;  //1
System.out.print(i+ " "+ k) ;

hi angeela
i am totally agree with silpi , its only to cofuse , + + or even hundred + means the same one + . Here first + for addition and second + for sign notation


code:

public class TestClass
{
public static void main (String args[ ] )
{
int k = 1;
int i = ++k + k++ + + k ;
System.out.print(i+ " "+ k) ;
}
}
/*
++k = 1 + 1 =2
k++ = 2+1=3
+k = +3


i = ++k(2) + k++(2) + +k(3);
i = 2 + 2 + 3 = 7
*/



The solution might be confusing.If is there any mistake then please tell me . cia
