Mar 4, 2024 · So the basic idea for converting a binary number to its decimal equivalent is to multiply each digit in the binary number by 2 raised to the power of its positional value and then add up these values. For example : Input: 1100. Output: 12. Below is a Java Code for the above-mentioned approach (Works both for String as well as integer Data Type ):

In this program, you'll learn to convert binary number to a decimal number and vice-versa using functions in Java.

Mar 8, 2025 · Given a binary number as input, we need to write a program to convert the given binary number into an equivalent decimal number. Examples : Explanation : The output of 7 for input 111 represents the decimal equivalent of the binary number 111. Explanation : The output of 10 for input 1010 represents the decimal equivalent of the binary number 1010.

Mar 26, 2023 · Binary to Decimal in java inbuilt function. To convert a binary number to a decimal equivalent number in Java, there is an inbuild function provided by java parseInt() which is available in the java.lang.Integer class.

Oct 21, 2014 · You can use Integer.parseInt(binaryNumber, 2) method to directly convert any binary number into decimal number, where binary is String. Use this code, which is more efficient to convert binary numbers into decimal numbers.

Write a Java program to convert binary to decimal. We can use the parseInt with two as the second argument will convert the binary string to a decimal integer. public static void main(String[] args) { String s1 = "1101"; String s2 = "10101"; String s3 = "11111"; String s4 = "110101"; System.out.println(Integer.parseInt(s1, 2));

There are mainly two ways to convert a binary number to decimal number in Java. 1. By using parseInt () method of Integer class. 2. By using user defined logic. By using Integer.parseInt () Integer.parseInt () method takes two arguments. First argument is a string and second argument is the base or radix in which we have to convert the number.

In this tutorial, we will explore how to create a Java program to convert a binary number to its decimal equivalent. This type of conversion is common in computing and digital electronics, as it allows us to move between different numeral systems.

Apr 1, 2025 · Convert a negative binary number to decimal. Modify the program to accept binary numbers up to 32 bits. Write a program to handle binary-to-decimal conversion without using loops.

Jan 15, 2025 · Converting a binary number to a decimal number is a basic operation in coding that helps us understand binary numbers and their connection to decimal numbers. In this post, we will learn what a binary number is, the steps to convert it to decimal, and write a Java method to perform this task.
