For loop is not giving values as per range

Question

       for(OPV=230;OPV<245;OPV++)
       {
           for(IKW=1.3;IKW<=2.9;IKW++)
           {
               for(OKW=0.01;OKW<0.50;OKW++)
              {
                     for(OPI=0.05;OPI<0.50;OPI++)
                     {
                           OPV=OPV+1;
                           IKW=IKW++;
                           OKW=OKW++;

                           System.out.println( OPV+""+IKW+"+OKW+"+OPI")

My for loop is not giving me result as per the ranges I have given.suggest some modifications if any

What ranges do you think you have given? **How** does this not meet your expectations? — Elliott Frisch, Apr 14 '16 at 12:18
What range of values do you want `for(IKW=1.3;IKW<=2.9;IKW++)` to represent? Do you want `1.3`, `1.4`, ..., `2.8`, `2.9`? Or only `1.3`, `2.3`? — Pshemo, Apr 14 '16 at 12:23
Then why are you using `IKW++` to increment its step? It is almost same as `IKW = IKW + 1` not `IKW = IKW + 0.1`. — Pshemo, Apr 14 '16 at 12:26
Also about `IKW=IKW++` read [What is x after “x = x++”?](http://stackoverflow.com/questions/7911776/what-is-x-after-x-x) — Pshemo, Apr 14 '16 at 12:28

When you increment the loop variable with OPI++, it is incremented by one. This means that the two inner most loops will have just one iteration.

You can set a smaller increment with, for example, OPI+=0.01, depending on your requirements.

Besides that, usually there's no point in incrementing the loop variables inside the loop body as you do, since that causes them to be incremented in both the loop's increment clause and the loop body.

Something like this may be what you want (though you may want to change the increments) :

for(OPV=230;OPV<245;OPV++) {
    for(IKW=1.3;IKW<=2.9;IKW+=0.1) {
        for(OKW=0.01;OKW<0.50;OKW+=0.01) {
            for(OPI=0.05;OPI<0.50;OPI+=0.01) {
                System.out.println(OPV + " " + IKW + " " + OKW + " " + OPI);
            }
        }
    }
}

i did that but it is exceeding value from range for opi – Pooja Apr 14 '16 at 12:29 — Pooja, Apr 14 '16 at 12:29
