In C, the language itself does not determine the representation of certain datatypes. It can vary from machine to machine, on embedded systems the int can be 16 bit wide, though usually it is 32 bit.
The only requirement is that short int <= int <= long int by size. Also, there is a recommendation that int should represent the native capacity of the processor.
All types are signed. The unsigned modifier allows you to use the highest bit as part of the value (otherwise it is reserved for the sign bit).
Here's a short table of the possible values for the possible data types:
width minimum maximum
signed 8 bit -128 +127
signed 16 bit -32 768 +32 767
signed 32 bit -2 147 483 648 +2 147 483 647
signed 64 bit -9 223 372 036 854 775 808 +9 223 372 036 854 775 807
unsigned 8 bit 0 +255
unsigned 16 bit 0 +65 535
unsigned 32 bit 0 +4 294 967 295
unsigned 64 bit 0 +18 446 744 073 709 551 615
In Java, the Java Language Specification determines the representation of the data types.
The order is: byte 8 bits, short 16 bits, int 32 bits, long 64 bits. All of these types are signed, there are no unsigned versions. However, bit manipulations treat the numbers as they were unsigned (that is, handling all bits correctly).
The character data type char is 16 bits wide, unsigned, and holds characters using UTF-16 encoding (however, it is possible to assign a char an arbitrary unsigned 16 bit integer that represents an invalid character codepoint)

In C, the integer(for 32 bit machine) is 32 bit and it ranges from -32768 to +32767.
Wrong. 32-bit signed integer in 2's complement representation has the range -231 to 231-1 which is equal to -2,147,483,648 to 2,147,483,647.

Integer MAX_VALUE in Java with Examples
December 10, 2024 - Integer.MAX_VALUE is a number in the Java Integer сlass of java.lang package. It is the maximum possible Integer number that can be represented in 32 bits. Its exact value is 2147483647 i.e.
Beginner here; please help with explaining why Integer.MAX_VALUE and Integer.MIN_VALUE is assigned as values in this code.
Think of only one, you are looking for the lowest number in an array, you take the first number and compare it to your minValue, if it is smaller you choose that as new minValue and try the next. If you start minValue as the absolute MIN_VALUE, it will never find a smaller number in your array. SO you should start minValue as higher as possible and maxValue as lover. (Or you can just initiate them as the first number in your array) More on reddit.com

July 4, 2022How to get the value of Integer.MAX_VALUE in Java without using the Integer class - Stack Overflow
I have this question that has completely stumped me. I have to create a variable that equals Integer.MAX_VALUE... (in Java) // The answer must contain balanced parentesis public class Exercise{ More on stackoverflow.com
Why Integer.MAX_VALUE + Integer.MAX_VALUE result in -2?
First off Integer.MIN_VALUE is -(231) and not 231 Integer.MAX_VALUE = 231 -1 = 2147483647. If we do the addition in binary we get: 1111111111111111111111111111111 +1111111111111111111111111111111 11111111111111111111111111111110 Which is -2 in decimal. As far as I remember the 32nd bit being 1 indicates that the number is negative. The binary representation of 231 - 1 takes 31 bits, the 32nd bit being 0. The operation of MAX_VALUE + MAX_VALUE overflows and makes the 32nd bit 1. To look at it another way.... Integer.MAX_VALUE + 1 = Integer.MIN_VALUE so Integer.MAX_VALUE + Integer.MAX_VALUE + 1 = Integer.MIN_VALUE + Integer.MAX_VALUE which implies Integer.MAX_VALUE + Integer.MAX_VALUE = Integer.MIN_VALUE + Integer.MAX_VALUE - 1 = -(231) + (231 -1) -1 = -(231) + (231) -1 -1 = -2 More on reddit.com

You want to test if the expression A * B > max is true, but you can't directly evaluate the term A * B because it might overflow, so adjust the inequality, perhaps A > max / B. (There could be rounding errors to account for.) Alternatively, you could compute A * B using a long. More on reddit.com

3.7. Integer Min and Max — AP CSA Java Review - Obsolete
In 32 bits of space with one bit used to represent the sign you can represent that many values. Why is there one more negative number than positive number? It is because 0 is considered a positive number. What do the last two lines print out? Did this surprise you? Java will actually return the maximum integer value if you try to subtract one from the minimum value.

r/learnjava on Reddit: Beginner here; please help with explaining why Integer.MAX_VALUE and Integer.MIN_VALUE is assigned as values in this code.
July 4, 2022 -
I was searching for a way to find the min and max value within a number of integers and I came across this code:
Scanner in = new Scanner(System.in);
int maxNum = Integer.MIN_VALUE;
int minNum = Integer.MAX_VALUE;
while (scanner.hasNextInt()) {
int num = scanner.nextInt();
maxNum = Math.max(maxNum, num);
minNum = Math.min(minNum, num);
}
System.out.println("The maximum number: " + maxNum);
System.out.println("The minimum number: " + minNum);I am struggling to wrap my mind around Integer.MAX_VALUE and Integer.MIN_VALUE. Why are they assigned as values and how does it work with the Math. min & max methods. Why is the variable maxNum assigned the value Integer.MIN_VALUE and minNum assigned the value Integer.MAX_VALUE?
Thanks.

What is Integer.MAX_VALUE?
Integer.MAX_VALUE represents the maximum positive integer value that can be represented in 32 bits (i.e., 2147483647). This means that no number of type Integer that is greater than 2147483647 can exist in Java.

Here's a succinct method:
int ONE = "x".length();
int i = -ONE >>> ONE; //unsigned shift
This works because the max integer value in binary is all ones, except the top (sign) bit, which is zero. But -1 in twos compliment binary is all ones, so by bit shifting -1 one bit to the right, you get the max value.
11111111111111111111111111111111 // -1 in twos compliment
01111111111111111111111111111111 // max int (2147483647)

As others have said.
int i = Integer.MAX_VALUE;
is what you want.
Integer.MAX_VALUE, is a "static constant" inside of the "wrapper class" Integer that is simply the max value. Many classes have static constants in them that are helpful.

October 30, 2011 - The symptom that @subone saw (only the last number printing) comes from consuming all input with repeated calls to nextInt() without storing each value. A later nextInt() does not "replay" earlier tokens; it reads the next token (or blocks). The simplest, robust pattern is: read each integer once, store it (an array is ideal), and update sum, max and min inside the same while loop.
