Write a java program to convert the string into boolean. Take the string from the user.

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.

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

Write a Regular expression that check whether a string contains an Vowel or not? You have also include the driver code in Java Language. Your driver code should take string from the user.

Write Java code to read strings of lower-case letters from the keyboard and count the number of vowels in each word. (vowels are a,e,i,o and u). When all strings have been read in, print the string that has the largest number of vowels (duplicates included) and how many vowels were in the string. When more than one string has the greatest number of vowels, print the first string found with that number. For example, with input of she groceries yourselves here radio, the correct answer would be: groceries – 4 vowels.

Create a method in JAVA that returns a string when it receives three ints

Design a java program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as : enter a string rizma This string has all the unique characters would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique

USING JAVA Implement two methods that: Capitalize the first letter of each word in the given text. Reverse the characters in the words that are in the odd positions of the original text. Add a test program that exercises these methods for a string with at least tenwords in it. For example: The original text is "learning javafx is fun! javafx is a powerful library." The result and reversed text will be "Learning xfavaJ Is !nuF Javafx sI A lufrewoP Library."

Write the code in java and please dont plagarise or copy from other sources write it on your own and read the question carefully and do what in the question says thank you.
