I need to write a java program but I can not use arrays.

Prelab Assignment 04 (Lab 07) CMPE 112 Fundamentals of Programming I, Fall 2017 You are given a long text to analyze it. You are asked to implement a Java program called TextStatistics.java that computes some word statistics. Given a text, you will compute: The number of sentences . The number of words The greatest word of the whole text ("Troy" is same with "troy", but it is greater than asia". ) The smallest word of the whole text (asia" is smaller than "troy".) The number of words with 1-2-3-4-5-more characters Your program gets a text as an input from the user and returns the statistics as below. Assume that the text entered has at least one sentence, each ending with a period ("."), and each sentence includes at least one word. The greatest and the smallest words will be printed in lower case (e.g., The greatest word :you). The sample outputs of the program are as below: Sample Outputs: Enter a text: You are given a short text. The # of sentences :1 The # of words :6 The greatest word :you The smallest word :a The # of words with 1 char :1 The # of words with 2 char :0 The # of words with 3 char :2 The # of words with 4 char :1 The # of words with 5 char :2 The # of words with >5 char:0
