Java string replace and the NUL (NULL, ASCII 0) character?

I’m doing some String algorithms in Java, and i noticed that wherever i include a char with the value of 0 (zero) it marks the end of the String. Like this:

String aString = "I'm a String";
char[] aStringArray = aString.toCharArray();
aStringArray[1] = 0;
System.out.println(new String(aStringArray)); //It outputs "I"

What’s the reason/cause of this behaviour?

Answer 1

The character '\0' is the null character. It’s a control character, and it does not terminate the string, that’s not how strings work in Java (that’s how they work in C, though.)
