What are the values stored in variables r1 and r2:

1. double r1 = Math.abs(Math.min(-2.83, -5.83));
2. double r2 = Math.sqrt(Math.floor(16.3));

1. r1 has 5.83
2. r2 has 4.0

Explanation

1. Math.min(-2.83, -5.83) returns -5.83 as -5.83 is less than -2.83. (Note that these are negative numbers). Math.abs(-5.83) returns 5.83.
2. Math.floor(16.3) returns 16.0. Math.sqrt(16.0) gives square root of 16.0 which is 4.0.
