Double increments in Java

How to iterate between 0.1f and 1.0f with 0.1f increments in Java?

Part of my program needs to use values inside a while loop as:

0.1

0.2

0.3

...

0.9

so I need to provide them inside that loop. Here is the code:

double x = 0.0;
while ( x<=1 )
{
// increment x by 0.1 for each iteration
x += 0.1;
}

I need the output to be EXACTLY:

0.1

0.2

0.3

0.4

0.5

0.6

0.7

0.8

0.9

But it actually gives me something like:

0.1

0.2

0.300000000000000000000000004

0.4

0.5

0.6

0.79999999999999999999999999

0.89999999999999999999999999

0.99999999999999999999999999
