Length and length () used to get the length in Java. I don't know the difference, so I summarized it.
It seems that the meaning is often confused even for non-beginners, so let's review it once.
length: Get the length of the array </ b> length (): Get the length of the string </ b>
For reference, use it like this.
public class Main {
public static void main(String[] args) {
//length: Get the length of the array
int[] array = {1, 2, 3};
System.out.println(array.length); // 3
// length(): Get the length of the string
String str = "length of length";
System.out.println(str.length()); // 9
}
}
By the way, when you get the length of a character string using length (), it is counted as one character regardless of whether it is full-width or half-width.
Let's implement the code after understanding which one you want to use. See you again
