The Integer.toString() method is typically used to convert an integer to a String. Also, Integer.toString() is preferred to String.valueOf(), because String.valueOf() ends up calling Integer.toString() anyway.
Do not write
int i = 8100; String s = String.valueOf(i);, because it is
inefficient to use
public static String valueOf(int i) {
from class String.
Use
public static String toString(int i) {
from class Integer instead.
public static String valueOf(int i) {
from class String simply calls
public static String toString(int i, int radix) {
from class Integer which in turn calls
public static String toString(int i) {
from class Integer.
Similarly, use code like
byte b = Byte.parseByte("35");
for converting bytes.
