Description html markup shown to student | Write a class <code>Boxed</code> whose API has two public static methods: <ul> <li>Write a method <code>repeat()</code> that takes a string argument and an integer argument, and returns the <code>String</code> obtained by repeating the string that many times. For example <code>repeat("hots", 2)</code> should return <code>"hotshots"</code> </li> <li>Using <code>repeat()</code>, write a method <code>boxedPrint()</code> that takes a string argument, and prints it out surrounded by a box of asterisks. For example, <code>boxedPrint("Hello, World!")</code> should cause the following text to be sent to standard output: <pre> *************** *Hello, World!* *************** </pre> To get the <b>length</b> of a String <code>stringVar</code>, use <code>stringVar.length()</code>. </li> </ul> |
