Write Java classes to implement the following: Problem 1. Input three strings s1, s2, and s3 from the keyboard such that s1 = "Hello out there. Howw are you this morning?" s2 = "Did you watch the movie that was on TV last night?" s3 = "Yes, we didd!" a. correct the spelling errors in s1 and s3 (find and replace) and re-display the strings. Also, replace "TV" with Netflix". I**II b. concatenate all 3 strings but insert between them. c. Print each string on a separate line d. print string s2 and s3 on the same line.

how to write a java program that determine if a string is a palidrome using a recursive method and a non-recursive method (ignore characters that are not letters). Then write a driver to test the two versions of the two methods. (A palindrome is a string that reads the same forward as well as backward. For example, “otto” and “never odd or even” are palindromes) (driver can be hard coded)

practice JAVA program that inputs a string from the user and prints a copy of the string with the first character of each sentence capitalized. (No need to consider strings with punctuation marks other than a period.) NOTE: For string and character manipulation, you should use only the String and Character methods (and not methods of other API classes) HINT: To split a string with “. “ delimiter, pass the following expression to the split method: “\\. “ String methods split, charAt, and substring, and Character method toUpperCase can be helpful.

Write the following programs in Java: In the Converter class write the static method, bin2decimal(String bin). The parameter for this method is an unsigned (nonnegative) binary number represented by a string. The method returns the decimal equivalent for the binary parameter, as an integer.If the binary string is invalid (contains characters other than ‘0’ and ‘1’), the method returns -1. Convert from a binary (b) string with up to 16 digits to decimal (d) using the following formula:? = ?0 + ?1 × 2 + ?2 × 22 +⋯+ ?7 × 215where b0, b1, ?2, … ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 + 0×2 + 1×22 + 1×23 = 13 in decimal. Side note: You may NOT use the decode method of the Long wrapper class instead of this formula.   In the Converter class write another static method, english2encrypted(String english). The parameter for this method is a word or sentence represented by a string. The word or sentence should only contain letters (no digits,…
