How to Declare Java Variables? The image below demonstrates how we can declare a variable in Java From the image, it can be easily perceived that while declaring a variable, we need to take care of two things that are data type In Java, a data type define the type of data that a variable can hold. variable name Must follow Java naming

Finally, let's see how null Strings behave. Let's declare and initialize a null String String nullValue null If we printed nullValue, we'd see the word quotnullquot, as we previously saw. And, if we tried to invoke any methods on nullValue, we'd get a NullPointerException, as expected. But, why does quotnullquot is being printed?

But character array and Strings are quite different in Java, declarations, operations and usages are different.

String string String.formatquotA String s 2dquot, aStringVar, anIntVar I'm not sure if that is attractive enough for you, but it can be quite handy. The syntax is the same as for printf and java.util.Formatter. I've used it much especially if I want to show tabular numeric data.
