Java-string class

Package com.day6.one;

public class Stringdemo {

/**
* @param args
* 1. String literal "abc" can also be seen as a string object
* 2. String is a constant, once assigned, it cannot be changed
*/
public static void Main (string[] args) {
String str= "ABC"; "ABC" can be seen as a string object
Str= "Def"; When the "Def" is assigned to STR, the original "ABC" becomes garbage.
System.out.println (Str.tostring ()); The string class overrides the ToString method to return the object itself
