Most of the times, in competitive programming, there is a need to assign the variable, the maximum or minimum value that data type can hold, but remembering such a large and precise number comes out to be a difficult job. Therefore, Java has constants to represent these numbers, so that these can be directly assigned to the variable without actually typing the whole number.
  • Integer.MAX_VALUE Integer.MAX_VALUE is a constant in the Integer class of java.lang package that specifies that stores the maximum possible value for any integer variable in Java. The actual value of this is 
    2^31-1 = 2147483647
    Example 1: Java 
    // Java program to show
// the value of Integer.MAX_VALUE

class GFG {

    // Driver code
    public static void main(String[] arg)
    {

        // Print the value of Integer.MAX_VALUE
        System.out.println("Integer.MAX_VALUE = "
                           + Integer.MAX_VALUE);
    }
}
    Output: 
    Integer.MAX_VALUE = 2147483647
    Any integer variable cannot store any value beyond this limit. Upon doing so, the memory will overflow and the value will get negative. Example 2: Trying to initialize a variable value Integer.MAX_VALUE + 1 Java 
    // Java program to show what happens when
// a value greater than Integer.MAX_VALUE
// is stored in an int variable

class GFG {

    // Driver code
    public static void main(String[] arg)
    {

        try {

            System.out.println(
                "Trying to initialize"
                + " a N with value"
                + " Integer.MAX_VALUE + 1");

            // Try to store value Integer.MAX_VALUE + 1
            int N = Integer.MAX_VALUE + 1;

            // Print the value of N
            System.out.println("N = " + N);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
    Output: 
    Trying to initialize a N with value Integer.MAX_VALUE + 1
N = -2147483648
  • Integer.MIN_VALUE Integer.MIN_VALUE is a constant in the Integer class of java.lang package that specifies that stores the minimum possible value for any integer variable in Java. The actual value of this is 
    -2^31 = -2147483648
    Example 3: Java 
    // Java program to show
// the value of Integer.MIN_VALUE

class GFG {

    // Driver code
    public static void main(String[] arg)
    {

        // Print the value of Integer.MIN_VALUE
        System.out.println("Integer.MIN_VALUE = "
                           + Integer.MIN_VALUE);
    }
}
    Output: 
    Integer.MIN_VALUE = -2147483648
    Any integer variable cannot store any value below this limit. Upon doing so, the memory will overflow and the value will get positive. Example 2: Trying to initialize a variable value Integer.MIN_VALUE - 1 Java 
    // Java program to show what happens when
// a value less than Integer.MIN_VALUE
// is stored in an int variable

class GFG {

    // Driver code
    public static void main(String[] arg)
    {

        try {

            System.out.println(
                "Trying to initialize"
                + " a N with value"
                + " Integer.MIN_VALUE - 1");

            // Try to store value Integer.MIN_VALUE - 1
            int N = Integer.MIN_VALUE - 1;

            // Print the value of N
            System.out.println("N = " + N);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
    Output: 
    Trying to initialize a N with value Integer.MIN_VALUE - 1
N = 2147483647
