java random number between 1 and 10

/* First Method */
int random = (int) (Math.random() * 100 + 1); /* Random number between 1 and 100*/
int random = (int) (Math.random() * 65 + 1); /* Random number between 1 and 65*/
/* Second Method */
import java.util.Random;
Random randnumber = new Random();
int number = randnumber.nextInt(100); /* between 1 and 100*/
system.out.println(number);

java random number generator 5

int unBitshiftRightXor(int value, int shift) {
  // we part of the value we are up to (with a width of shift bits)
  int i = 0;
  // we accumulate the result here
  int result = 0;
  // iterate until we've done the full 32 bits
  while (i * shift < 32) {
    // create a mask for this part
    int partMask = (-1 << (32 - shift)) >>> (shift * i);
    // obtain the part
    int part = value & partMask;
    // unapply the xor from the next part of the integer
    value ^= part >>> shift;
    // add the part to the result
    result |= part;
    i++;
  }
  return result;
