How to create this Java program?

Anyone knows how to create a java program?

• Many word processing applications require text to be left justified and formatted in such a way that no line has length exceeding the width of the text area. Words, that is, sequences of characters containing no white space, cannot be split across lines. To simplify this problem, we can assume that all characters have equal width and that a line has a fixed number of columns. If the number of columns in a line is 10, for example, then the text: Now is the time for all good people to come to the aid of their country. No one should be exempted, I say. would be reformatted as: Now is the time for all good people to come to the aid of their country. No one should be exempted, I say. If the number of columns is 20, the output is: Now is the time for all good people to come to the aid of their country. No one should be exempted, I say. Any word that is too long to fit on a line will be on a line by itself. Write a program whose input is a sequence of words read from a source file called “unjustified.txt” and whose output is that same sequence, justified to fit lines that have 20 columns. Keep in mind that the input sequence of words may span multiple lines in the source file with each line being composed of any number of words per line. Your program should be submitted as Justify.java. Magic number alert!!! The number 20 should not appear anywhere in your program, except as the value of a constant declared at the beginning; in other words, write your program so that changing the number of columns will be easy to do. You may want to keep several test input files as you refine your program.
