Scientific Numbers in Java are numbers that use the scientific notation, which is a way of expressing numbers as the product of a coefficient and a power of 10. In Java, scientific numbers are represented by using the letter "E" or "e" to indicate the exponent.
Here is an example code that demonstrates the use of scientific notation in Java:
double d1 = 1.2E3; // same as 1.2 x 10^3 or 1200.0
double d2 = 1.23e-4; // same as 1.23 x 10^-4 or 0.000123
