java programming
This problem set will test your knowledge of System I/O, and variable assignment. Your task is to create several different java classes (.java files) that will produce a specific output based on the user input. All input will be given to you either as a command-line argument or typed in from the keyboard.
Below you will find directions for each class you need to create. Please make sure that the class name and java file name match the name specified in the directions below. For example, the code for the problem named "ContainsAycase" should be put in a java file name ContainsAnycase.java and that file should have a class named public class ContainsAnycase.
ContainsAnyCase
This program will accept two user inputted values that are strings. The first user input will be a single word the second user input will be a sentence of random words. This program should print "true" if the first word is in the sentence of words regardless of the casing. In other words case is ignored when checking if the word is within the sentence. The last string that this program should print is "true" or "false", nothing else.
PairGreaterLesser
This program will accept four user inputted values that are numbers. The first two inputted values make a pair and the third and fourth inputted values make another pair. This program should print "true" if the first number is less than the second number and the third number is less then the fourth number and the sum of the first pair is less than the sum of the second pair, it should print "false" otherwise. The last string that this program should print is "true" or "false", nothing else.
NthCharacter
This program will accept two user inputted values. The first user inputted value is a number and the second user inputted value is a sentence of words. The program should print the character at the index associated with the first value found in the sentence of words. The last string that this program should print is the character at the specific index, nothing else.
