The 1.1 version of Java introduces a number of classes for dealing with characters. These new classes create an abstraction for converting from a platform-specific notion of character values into Unicode values. This column looks at what has been added, and the motivations for adding these character... 4.2. Strings and Characters. Strings of text are a fundamental and commonly used data type. In Java, however, strings are not a primitive type, like char, int, and float.

To create this article, 21 people, some anonymous, worked to edit and improve it �... 19/07/2015�� Here is our Java program, which combines all the ways we have seen to convert String and character to their respective ASCII values. You can also use the same technique to convert String to other encoding formats e.g. ISO-8859-X (1-7) , UTF-8 , UTF-16BE , UTF-16LE. These are some of the popular encoding formats internally supported by Java.
Firstly, there's a slight difference in semantics. If a is null, then a.concat(b) throws a NullPointerException but a+=b will treat the original value of a as if it were null.
12/02/2013�� Best Answer: Just another note about Strings in Java. The fast way is to use concatenation. But, keep in mind that Java indexes each uniqueString you create, so if you're doing this repeatedly or you're concatenating a lot of values, each + operation creates a new object in memory.
