Java: Convert String to Binary

In this code example, we take a look at how to convert a String to Binary in Java with examples.

Example 1:

package org.code2care.java.examples;

public class ConvertStringToBinary {

    public static void main(String[] args) {

        String userString = "Hello World!";
        StringBuilder binaryStringBuilder = new StringBuilder();

        for (char ch : userString.toCharArray()) {
            String binary = Integer.toBinaryString(ch);
            binaryStringBuilder.append(String.format("%8s", binary).replace(' ', '0'));
        }
        System.out.println(binaryStringBuilder.toString());

    }
}

Output:
Example 2:

package org.code2care.java.examples;

public class ConvertStringToBinary {

    public static void main(String[] args) {

        String userString = "Hello World!";
        StringBuilder binaryStringBuilder = new StringBuilder();
        for (char ch : userString.toCharArray()) {
            String binaryString = String.format("%8s", Integer.toBinaryString(ch)).replace(' ', '0');
            binaryStringBuilder.append(binaryString);
        }
        System.out.println(binaryStringBuilder.toString());


    }
}
