I need to create a method to geneate random (single) letter and return it as String, not as a char.
I saw solutions like this creating random char. But I need my method to return a String type.
I managed to build the following method:
public static String randomLetter(){
int num = intInRange(0, 26) + 97;
char [] temp = new char[1];
temp[0] = (char) num;
return new String(temp);
}
基于我们项目中已有的方法
public static int intInRange(int min, int max) {
Random rnd = new Random();
return rnd.nextInt(max - min) + min;
}
But I do not like what I currently have since I'm creating too many temporary variables to achieve the goal.
Is there a way to get similar result in a shorter way to avoid usage of char [] temp ?
