    copied!<p>I wrote a method that loops through a string and adds '/n' to create a line length that was given in the parameters. That description is not the best but it's hard to describe so look at the code below. Thanks in advance!</p> <p>My Code: </p> <pre><code>public static String lineLength(String str, int length){ int totalLength = 0; //total length of the document int lengthConst = 0; //constant value of the length for the loop int nLength = 0; // length of \n = 2 characters String work1, work2; //Strings to work with in the loop. Used as string buffers in substrings if(str != null){ totalLength = str.length(); lengthConst = length; } if(length &lt; 1){ throw new NullPointerException("Length must be &gt;= 1"); } /* Main Loop: check again if length is not zero, check if totalLength is not zero, check if pseudoCursor is not zero, check if length is less than or equal to totalLength */ while((length != 0) &amp;&amp; (totalLength != 0) &amp;&amp; (lengthConst != 0) &amp;&amp; (length &lt;= totalLength)){ work1 = str.substring(0, length); //store string of beginning to line length work2 = str.substring(length + nLength, str.length()); //store string from length to end work1 = work1.concat("\n"); //add new line str = work1.concat(work2); //add work1 and work2 and store in str nLength += 1; //nLength increases by 2 because we are going to add another \n length += length; } return str; } </code></pre> <p>When provided with the string "Daniel" and the new line length of 2 this is the run when printed to the console:</p> <pre><code>run: Da n el BUILD SUCCESSFUL (total time: 4 seconds) </code></pre>
