    The Math class is another frequently used class that contains several methods: abs( ) returns the absolute value round( ) rounds to the nearest whole number ceil( ) rounds up floor( ) rounds down max(x, y) returns the larger value of x and y min(x, y) returns the smaller value of x and y pow(x, y) returns x to the power of y random( ) returns a double in the range [0, 1.0) sqrt( ) returns the square root

Slide 2

    Static Methods
    The methods in the Math class are static. Static means that the methods do not require the creation of an object in order to invoke them. They are invoked through the class name. Static methods are used when we will have the same result regardless of the object. For example, the abs( ) method will compute the absolute value of the number given every time. No individual object will change that computation.  Most Math methods will return a double value, however, there are some that return integers.

    Examples
    System.out.println(Math.abs(-3)); System.out.println(Math.ceil(4.201)); System.out.println(Math.floor(5.511)); System.out.println(Math.max(1, -4)); System.out.println(Math.abs(-2, 0)); System.out.println(Math.pow(2, 3)); System.out.println(Math.round(3.59)); System.out.println(Math.sqrt(529)); System.out.println(Math.abs(-3));
