I am unable to understand the solution of this Question??
Please Explain

What is the output
{
Float f1 = new Float("4.4e99f");
Float f2 = new Float("-4.4e99f");
Double d1 = new Double("4.4e99");
System.out.println(f1);
System.out.println(f2);
System.out.println(d1);
}

a) Runtime error

floats have a range of something like 1e-45 to 1e38 (positive or negative). So 4.4e99 and -4.4e99 are out of that range, so the value becomes infinity.
