In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and methods useful when dealing with an int.. It is the maximum possible Integer number that can be represented in 32 bits. Following are the minimum and maximum value of primitive data types in Java: Lets now see some examples to display the minimum and maximum value of primitive data types: We work to create programming tutorials for all. The value of the argument can be recovered from the Its default value is 0. This method returns the int equivalent of this Integer object. Integral types may be unsigned (capable of representing only non-negative integers) or signed (capable of representing negative integers as well).. An integer value is typically specified in the source code of a program as a sequence of digits Returns the value of this Integer as a long. If you continue to use this site we will assume that you are happy with it. The following example illustrates an aggregate operation using Stream and IntStream, computing the sum of the weights of the red widgets: int sum = widgets.stream() .filter(w -> w.getColor() == RED) .mapToInt(w -> WebMaximum and Minimum Value of Integer.
