Write code to create a method to compare two string values and handle null
//package com.book2s; public class Main { public static void main(String[] argv) { String str1 = "book2s.com"; String str2 = "book2s.com"; System.out.println(compare(str1, str2)); }/*from w w w.j av a 2 s .c om*/ public static boolean compare(String str1, String str2) { if (str1 == null) { if (str2 != null) { return false; } } else { return str1.equals(str2); } return true; } public static boolean equals(String str1, String str2) { if (str1 == null) { if (str2 != null) { return false; } } else if (!str1.equals(str2)) { return false; } return true; } }
