java.util.Math is a package library in Java that contains various mathematical functions. These functions include elementary mathematical operations such as addition, subtraction, multiplication, and division, as well as more complex operations such as exponentiation, trigonometric functions, logarithmic and exponential functions, square roots, and more. This package library is used to perform mathematical calculations in Java programs.
Here are some code examples utilizing java.util.Math:
1. Finding the square root of a number:
`double num = 25;`
`double result = Math.sqrt(num);`
`System.out.println("The square root of " + num + " is " + result);`
Output: The square root of 25 is 5.0
2. Rounding a floating-point number to the nearest integer:
`double num = 3.7;`
`int result = (int) Math.round(num);`
`System.out.println("The rounded integer value of " + num + " is " + result);`
Output: The rounded integer value of 3.7 is 4
3. Calculating the sine of an angle:
`double angle = 30;`
`double radians = Math.toRadians(angle);`
`double result = Math.sin(radians);`
`System.out.println("The sine of " + angle + " degrees is " + result);`
Output: The sine of 30 degrees is 0.5
In conclusion, java.util.Math is a useful package library in Java that provides various mathematical functions for performing calculations in Java programs. The functions in this package allow programmers to perform complex mathematical operations with ease.
