Using java create a GUI scientific calculator? e.g find logarithm, Factorial, Square Root, etc in the form of GUI with Buttons

Features of Java Scientific Calculator

The following GUI java calculator will be able to perform the following task:

1. Addition(): To add one or more numbers.
2. Subtraction(): subtract the numbers.
3. Divide(): Divide the two numbers.
4. Multiplication(): multiplication of numbers.
5. Sin Value(): Get the value in radians as well as the degree of Sin.
6. Cos Value(): Get the value in radians as well as the degree of Cos.
7. Tan Value(): Get the value in radians as well as the degree of Tan.
8. Log Value(): Find the value of Log Using Math.log() funtion.
9. Factorial(): Calculate the factorial of a given number.
10. Square Root(): Find the square root of numbers. e.g. √36 is 6.

Java Scientific Calculator Program

In the following program, we use a package called javax.swing.*;, java.awt.*; and java.awt.event; . Which helps in to performs an event and creating a GUI component as shown in the output.
