Cómo generar una cuerda grande al azar en Java
// Java program generate a random
// UpperCase or LowerCase or Number String
import java.util.*;
public class GFG {
static String getAlphaNumericString(int n)
{
// lower limit for LowerCase Letters
int lowerLimit = 97;
// lower limit for LowerCase Letters
int upperLimit = 122;
Random random = new Random();
// Create a StringBuffer to store the result
StringBuffer r = new StringBuffer(n);
for (int i = 0; i < n; i++) {
// take a random value between 97 and 122
int nextRandomChar = lowerLimit
+ (int)(random.nextFloat()
* (upperLimit - lowerLimit + 1));
// append a character at the end of bs
r.append((char)nextRandomChar);
}
// return the resultant string
return r.toString();
}
public static void main(String[] args)
{
// size of random alphanumeric string
int n = 20;
// Get and display the alphanumeric string
System.out.println(getAlphaNumericString(n));
}
}
