Starting with Java 8, one could also take advantage of the join() method provided by the String class to print out array elements, without the brackets, and separated by a delimiter of choice (which is the space character for the example shown below):
The method is easy to use and the format pattern is defined by underlying formatter. String step1 = "one"; String step2 = "two"; // results in "Step one of two". String string = String.format("Step %s of %s", step1, step2); You can pass a Locale to respect the language and regional specification.
30. You're getting the toString() value returned by the Scanner object itself which is not what you want and not how you use a Scanner object.

//The class name should be the same as your Java-file and directory name. class iAmABoy { //Create a variable number of String-type arguments, "strs"; this is a useful line of code worth memorizing. public static void nlSeparated(String... strs) { //Each argument is an str that is printed.
Jul 12, 2011 · JavaDoc: String java.lang.Enum.name() Returns the name of this enum constant, exactly as declared in its enum declaration. Most programmers should use the toString method in preference to this one, as the toString method may return a more user-friendly name.
The way I know how to convert an integer into a string is by using the following code: Integer.toString(int); and. String.valueOf(int); If you had an integer i, and a string s, then the following would apply: int i; String s = Integer.toString(i); or. String s = String.valueOf(i);
16. You either need to use + to concatenate, or use String.format to format a string or similar. The easiest is to do concatenation: System.out.println("randomtext" + var); Some people often use System.out.printf which works the same way as String.format if you have a big messy string you want to concatenate:
