Convert Binary to Text in Java - Easy Tutorial

If you need to convert binary to text in Java, there are a few simple ways to achieve this. One common method is to use the built-in Java libraries to read the binary data and convert it to a readable text format.

One approach is to read the binary data as bytes and then convert these bytes to characters using the ASCII encoding. Here is an example code snippet that demonstrates how to do this:

public static String binaryToString(String binary) {
    StringBuilder stringBuilder = new StringBuilder();
    for (int i = 0; i < binary.length(); i+=8) {
        int character = Integer.parseInt(binary.substring(i, i + 8), 2);
        stringBuilder.append((char)character);
    }
    return stringBuilder.toString();
}

This code takes a binary input as a string and converts it to a readable text format by parsing the binary data into bytes and then converting these bytes to characters using the ASCII encoding.

Another approach is to use the Java Base64 class, which provides methods for encoding binary data as text. Here is an example code snippet that demonstrates how to use the Base64 class to convert binary data to text:

import java.util.Base64;

public static String binaryToString(String binary) {
    byte[] bytes = new BigInteger(binary, 2).toByteArray();
    return Base64.getEncoder().encodeToString(bytes);
}

This code takes a binary input as a string and converts it to a readable text format by first converting the binary string to a byte array using the BigInteger class and then encoding this byte array using the Base64 class.

In summary, there are several approaches to convert binary to text in Java, including parsing the binary data as bytes and converting to characters using the ASCII encoding, or using the Java Base64 class to encode the binary data as text. With these methods, converting binary to text in Java can be a straightforward process.
