Understanding Integer Class Methods [Integer.MIN_VALUE(),Integer.MAX_VALUE(),compareTo(),equals()] in Java using Eclipse IDE

In this tutorial, you will learn the following:

• Integer Class Methods
  • Integer.MIN_VALUE()
  • Integer.MAX_VALUE()
  • compareTo()
  • equals()

You would need the following inorder to following this tutorial:

• An Integrated Development Environment(IDE) installed that can run Java (e.g Netbeans, Eclipse)
• JDK 1.X installed on your Pc
• Of course willingness to learn

Difficulty

• Intermediate

Description

In this tutorial,firstly, the maximum and mimum value that an Integer can take was shown using the Integer.MAX_VALUE() and Integer.MIN_VALUE() methods respectively and also the compareTo() method was used to compare two Integer values together.
The equals() method is used to indicate if two Integers are of the same value.
The compareTo() method returns the following:

• 1: For when the Integer a is being compared with Integer b and a is greater.
• 0: For when the Integer a is being compared with Integer b and they are the same.
• -1: For when the Integer a is being compared with Integer b and b is greater.
