# Converting Binary to Hexadecimal Using a String Method in Java

## How can you convert from binary to hexadecimal using a string method in Java?

What is the process of converting binary to hexadecimal in Java?

## Answer:

To convert from binary to hexadecimal in Java, you can use the `Integer` class and its `toHexString()` method. First, convert the binary string to an integer using the `parseInt()` method with a radix of 2. Then, use the `toHexString()` method to convert the integer to a hexadecimal string.

To convert from binary to hexadecimal in Java, you can follow these steps:

## 1. Convert Binary String to Integer

First, you need to convert the binary string to an integer using the `parseInt()` method of the `Integer` class. The `parseInt()` method takes two arguments: the binary string and the radix, which is 2 for binary.

## 2. Convert Integer to Hexadecimal String

Once you have the integer value, you can use the `toHexString()` method of the `Integer` class to convert it to a hexadecimal string. The `toHexString()` method takes the integer value as input and returns a string representation of the hexadecimal value.

## 3. Utilize Hexadecimal String

Finally, you can print or use the hexadecimal string as needed in your Java program.

Here is an example code snippet:

**String binary = "101010";**

**int decimal = Integer.parseInt(binary, 2);**

**String hexadecimal = Integer.toHexString(decimal);**

**System.out.println(hexadecimal);**

This code will convert the binary string "101010" to its hexadecimal representation, which is "2A". The `parseInt()` method converts the binary string to an integer, and the `toHexString()` method converts the integer to a hexadecimal string.
