Who can handle the problem?

[Steven Gao]

Code as follows:
public class testing{
public static void main(String argv[]){
double ii=123456789.12345;
System.out.println("ii="+ii);
}
}
The output is: ii=1.2345678912345E8
But I want to get: ii=123456789.12345
How can I do it? Is it any function to solve it?

By default, numbers are formatted in scientific notation. The class java.text.DecimalFormat will help you do what you expect.
