Will Java's int always and everywhere be a 32 bit signed integer?

** first off I should ask: **
Does anyone knows of a current implementation 126b UINT for Java ?
I need something to hold natural cardinal values. ie: A huge counter.

I heard that using short s on 32bit system is just more inefficient than using int s. Is this the same for int s on a 64bit system?
Python recently(?) basically merged int s ... 
I am calculating the int equivalent of a given set of bits and storing that in memory. From there, I would like to determine all 1 value bits from the original ... 
I want to use Preon for project that communicates with a server written in C. The protocol depends on the native endianess of the machine (you can solve with ... 
I'm looking at an app in java that runs on both 32bit and 64bit systems, and it deals mainly with IP addresses. These IP addresses are kept as integers, and ... 
I'm revisiting a question (How to test if numeric conversion will change value?) that as far as I was concerned was fully solved. The problem was to detect when a ... 
I think I need a utility method like this:
public static short bitValue(int intNum, short pos)
{
short bitValue = 0;
//check pos bit (from right to ...

We divided an int to save three values into it. For example the first 8 bits (from left to right) hold one value, the 8th to 12th bits hold another value ... 

I'm writing a very computationally intense procedure for a mobile device and I'm limited to 32bit CPUs. In essence, I'm performing dot products of huge sets of data (>12k signed 16bit ... 
Is the value of Integer.MAX_VALUE different between 32bit JVMs and 64bit JVMs?
I am compiling a Java class using 32bit JDK and deploy it on a 64bit machine. I just want to ... 
I have an int and I want to invert the bits of it using the ~ bit operator. This should be a very simply thing to do, however I tried and ... 
1) how would I represent unsigned 8 bit integers in Java? Can I do this using a type or should I use byte, write out the value in unsigned 8 bit binary, and then reverse out the 2's complement to get the value? As an example 16 decimal = 0001 0000 and that works fine as it's not a 2's complement ... 
I'm having some trouble with some pretty basic stuff, and I was hoping someone could give me a hand. I need to write a program that asks the user to enter an integer and bit position. The program then needs to write out the value of the bit in that position of the integer (1 or 0). I know this sounds ...

Thanks for reply. Following is my algorithm (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11 Yes, it is basics and I believe I learnt in 5th grade . I know on a piece of paper, I can calculate. 1 0 1 1 But in ... 
I am using the Integer.toBinaryString() method to convert ints between 1 and 14 into binary.I would like them to be 4 bits long every time, i.e 2 = 0010. At the moment a 2 would be represented as 10. I need them as 4 bits because i will be concatenating 6 of these binary strings together, and losing length will completely ... 
What's the format of the bits? If it's binary bits (not encoded) then put the bits in a string and use Integer.parseInt. If the bits are encoded, then you'll need to interpret the bits  Java can interpret IEE754 formats using Double.longBitsToDouble. I don't believe any other encodings are provided by standard Java.

The most significant digit is always the one that has the highest influence on the value. In the (decimal) number 123 the most significant digit is 1, because changing it to anything else changes ... 
jschell wrote: Just a suggestion but you might find it reasonable for that problem domain to do it yourself. Certainly a lot of work but possible. You would probably see it sooner than with the RFE. Probably help the RFE along to see how feasible it is. Imagine 128bit long to be easier to implement first. Actually this would be the ... 
Is there someway of converting int values to a set number of bits without affecting the other bits in the byte. If I have a byte and I the first 3 bits are reserved and the other 5 bits represent a number. So I need convert a number to the 5 bits without changing the values in the first 3 bits. ... 

I want to create a unique hashcode/digest integer value (32bit integer). Input data is strings. Possible input values are "123", "131", "131_a", "131_b", "144_12_a", "144_12_b", ... Requirements: * digest/whatever method should return an integer * Same input should give the same integer in all JVMs (jdk1.1, jdk1.6, jdk1.7, ...) at any time * No collisions I was first about to use ... 

I understand that the character range is 0255 I want to create new charaters like "ab" which i would give a value of 256. I want to output the value 256 to a .dat file using DataOutputStream. However the character that is outputted to the .dat file has a value of 1 instead of 256. So i think the 256 value ...
