In order to convert a String to byte[] array in Java make use of the .getBytes() method from the String class,
Example:public class JavaStringToByteArray {
public static void main(String[] args) {
String string = "Hello World!";
byte[] byteArr = string.getBytes();
for(int i = 1;i <byteArr.length; i++) {
System.out.print(byteArr[i]+" ");
}
}
}
Output:
101 108 108 111 32 87 111 114 108 100 33 %
