Use java to write a code that implements the four arithmetic operations of decimals, trigonometric functions, and positive numbers

The Java language can be used to realize the four arithmetic operations of decimals, trigonometric functions and positive numbers. You can use the BigDecimal class in java to implement decimal operations, and use the Math class to implement trigonometric functions and four arithmetic operations on positive numbers. In addition, you can use Java's built-in operators to implement four arithmetic operations, such as addition, subtraction, multiplication, and division.
