Short solution:

xxxxxxxxxx
 
int MIN_VALUE = Integer.MIN_VALUE;
​
System.out.println(MIN_VALUE); // -2147483648

Java Integer min value is -2,147,483,648.

Short solution to get int max value:

xxxxxxxxxx
 
int MAX_VALUE = Integer.MAX_VALUE;
​
System.out.println(MAX_VALUE); // 2147483647

Java Integer max value is 2,147,483,647.

1. Different ways of how to get Integer min value

Edit

xxxxxxxxxx
 
public class Example1 {
​
    public static void main(String[] args) {
​
        int MIN_VALUE = Integer.MIN_VALUE;
        System.out.println(MIN_VALUE);   // -2147483648
​
        int MIN_VALUE_2 = (int) Math.pow(2, 31) + 1;
        System.out.println(MIN_VALUE_2); // -2147483648
​
        int MIN_VALUE_3 = -1 << 31;
        System.out.println(MIN_VALUE_3); // -2147483648
​
        int MIN_VALUE_4 = ~(~0 >>> 1);
        System.out.println(MIN_VALUE_4); // -2147483648
    }
}

Output:

xxxxxxxxxx
 
-2147483648
-2147483648
-2147483648
-2147483648

2. Integer overflow example

Edit

public class Example2 {
​
    public static void main(String[] args) {
​
        int MIN_VALUE = Integer.MIN_VALUE;
        int overflow = MIN_VALUE - 100;
        System.out.println(overflow); // 2147483548
    }
}
