Java Math Class in Java
The java.lang.Math class provides static utility methods for mathematical operations. It is auto-imported — no import statement needed.
Key methods: Math.abs() (absolute value), Math.pow(base, exp), Math.sqrt(), Math.ceil(), Math.floor(), Math.round(), Math.max(), Math.min().
Math.random() returns a random double in [0.0, 1.0). To get a random int from 0 to n-1: (int)(Math.random() * n).
Math.PI and Math.E are built-in constants (double precision). Use them instead of hardcoding 3.14159.
