Additionally, since this method supports a variety of object types, this method is flexible enough to be easily applied to various use cases. For example, if String.valueOf(x) is called on a variable that has not been initialized to a value, the function returns a null string instead of throwing a null pointer exception. It also provides protection against calls on null objects. Object types such as Integer, Float, Double, and Long are also supported. Primitive types include int, float, double, and long. Using the String.valueOf() method, developers can get the string value of various numeric primitive types and objects. In this article, we'll discuss several methods to convert int to string in Java, and as a bonus we'll touch on conversion from other numeric data types as well. The toString() method of Java Integer class is used to get a String object representing the value of the Number Object.There are three different types of Java toString() method which can be differentiated depending on its parameter. ![]() ![]() For example, you might need to include a number in a formatted string such as a debug message or a text field. The way I read the question, theyre more than happy with getting the string representation of the ArrayList (i.e. When working with numerical values such as integers, floats, doubles, and longs in Java, it's often necessary to convert them to strings.
