What is the easiest way in java to get the binary representation of an integer as a binary number with a fixed number of bits (For example, if I want to convert 3 with 5 bits, then the result would be 00011). In matlab, I can just specify the number of bits as an argument.

To convert integer to binary, start with the integer in question and divide it by 2 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero. Then just write out the remainders in the reverse order.
To convert int to binary in Python, use the bin() method. The bin() is a built-in Python method that converts a decimal to a binary data type. The bin() function accepts a number as an argument and returns its equivalent binary string prefixed with “0b”.
Java's Integer class has a method named toBinaryString to convert an integer into its binary equivalent string.

Using Inbuilt Method- toBinaryString() of the Integer class of Java. Approach 1: Using Implementation of Stack. Actually, the binary number consists of only 0 and 1. To convert an integer to binary divide the number by 2 until it becomes 0. In each step take the modulo by 2 and store the remainder into an array or stack.
Then, you’ll learn how to use four different methods to use Python to convert int to binary. These include, the bin () function, string formatting, f-strings, the format () function, as well as naive implementation without the use of any functions. What are Binary Strings for Integers?
Binary Value: The calculator returns the binary string equal to the value of the input integer. Binary numbers are comprised of zeros (0) and ones (1). The position of the zero or one indicate the exponent of two added to the value, making binary a base 2 number system
This is a simple way:
String binaryString = Integer.toBinaryString(number);
binaryString = binaryString.substring(binaryString.length() - numBits);
Where number is the integer to convert and numBits is the fixed number of bits you are interested in.

If you want to convert an int into its binary representation, you need to do this:
String binaryIntInStr = Integer.toBinaryString(int);
If you want to get the bit count of an int, you need to do this:
int count = Integer.bitCount(int);
But you couldn't get the binary representation of an integer as a binary number with a fixed number of bits , for example, 7 has 3 bits, but you can't set its bit count 2 or 1. Because you won't get 7 from its binary representation with 2 or 1 bit count.
