Write a Java method to display the middle character of a string. Note: a) If the length of the string is odd there will be two middle characters. b) If the length of the string is even there will be one middle character.

public class MiddleCharacter {
public static void main(String[] args) {
displayMiddle(“350”);
}

public static void displayMiddle(String str) {
int position;
int length;
if (str.length() % 2 == 0) {
position = str.length() / 2 – 1;
length = 2;
} else {
position = str.length() / 2;
length = 1;
}
System.out.println(str.substring(position, position + length));
}
}

Output:
