Write in Java
Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1.
Ex: If the input is:
Q. Hi andre
Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization.
For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not.
Your program should take a string as input and return true if it's a palindrome, and false otherwise.
Ok.
Language: Java
Write a program that takes a String as input from the keyboard, representing a year. Your program should do the following:
If the year entered has two characters, convert it to an int, add 2000 to it, and output it.
If the year entered has four characters, just convert it to an int and output it.
If the year entered has neither two nor four characters, output that the year is not valid.
