String conversion functionality

/* * String conversion function: * byte[] getBytes (): Converts the string to a byte array. * char[] ToCharArray (): Converts a string to a character array. * Static string ValueOf (char[] CHS): Turns the character array into a string. * Static string valueOf (int i): turns data of type int into a string. * Note: The valueof method of the string class can turn any type of data into a string. * String toLowerCase (): Turns the string into lowercase. * String toUpperCase (): Turns the string into uppercase. * String concat (String str): Concatenation of strings. */public class Stringdemo {public static void main (string[] args) {//define a String object As String s = "javase";//byte[] GetBytes (): Put the word String into a byte array. byte[] bys = S.getbytes (); for (int x = 0; x < bys.length; + x + +) {System.out.println (bys[x]);} System.out.println ("----------------");//char[] ToCharArray (): Converts a string to a character array. char[] CHS = S.tochararray (); for (int x = 0; x < chs.length; × x + +) {System.out.println (chs[x]);} System.out.println ("----------------");//static String ValueOf (char[] CHS): Turns the character array into a string.
