Hello, I have a current assignment to make a program copy what is put in, and place it into a paragraph using word wrap. If there is no room for the word+ a space then print the line and that word+ space starts the next line.
public class ReportWriter {
private String author;
private int noColumns;
private int noRows;
public ReportWriter(int noColumns, int noRows, String author) {
super();
this.author = author;
this.noColumns = noColumns;
this.noRows = noRows;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public void printParagraph(String msg){
String line = "";
while (msg.length() > 0) {
int spaceInx = msg.indexOf(' ');
if (spaceInx < 0) {
System.out.println(msg);
msg = " ";
} else if (spaceInx == 0) {
msg = msg.substring(1);
} else {
String word = msg.substring(0, spaceInx);
msg = msg.substring(spaceInx + 1);
// check if there is space on the for the word and a space
if (line.length() > noColumns){
}
// no room print the line and set line to "";
if (line.length() >0) {
line += " ";
}
line += word;
}
}
System.out.print(line);
// print remaining line
}This is the test class. There is more to it but it should wrap 50 chars in.
public class Test {
public static void main(String[] args) {
ReportWriter reportWriter = new ReportWriter(50, 20, "Smith");
reportWriter.printParagraph("Java was developed by Sun Microsystems in 1995 (Sun 1995). It is an object oriented language that was derived from C and C++. ");
}
}
