Basic Java Programming Math Functions Write a Java program that allow the user to input for the two angles A, and B (all in degrees), and the side a of an oblique triangle. Thereafter, solve for the triangle using laws of sine. Draw the user interface. Note: The sum of the interior angle of a triangle is always equal to 180. TEST CASE #1 TEST CASE #2 sin A + + sin B sine C Enter Angle A: 60 Enter Angle B:100 Enter Side a: 40 Angle C: 20.0 Enter Angle A: 50 Enter Angle B: 80 Enter Side a: 100 Angle C: 50.0 Side b: 128.5575 Side c: 100.0000 String Write a Java program to find a certain character in a string and replace it with a new character. Allow user to enter a string, find character and the replace character. Display the new string. TEST CASE #1 Enter a string: AABBCCDDD Find a character: A Replace with: S New String: SSBBCCDDD Array Write a Java program to find frequency of each character in a given string. Also display the length and the most frequent among the characters TEST CASE #1 Enter a string: AAABBBBCCCCC A=3 B=4 C=5 Length 12 Most Frequent = C Basic Java Programming Math Functions Write a Java program that allow the user to input for the two angles A, and B (all in degrees), and the side a of an oblique triangle.
