A test cilik ing String

Aku menehi perhatian sampeyan siji pitakonan cilik sing ditakoni ing "penerbangan" sing diarani nalika latihan. Ana bab-bab sing ora pati penting, nanging uga ana sing ora pati penting, sing dakkarepake. Dadi, diwenehi kode, sampeyan kudu nulis apa sing bakal dadi output menyang konsol lan nerangake apa sebabe. public static void main(String[] args) { String s1 = "AB"; String s2 = "A" + "B"; String s3 = new String("AB"); System.out.println(s1 == s2); System.out.println(s1 == s3); System.out.println(s1.equals(s2)); System.out.println(s1.equals(s3)); System.out.println(s1.toString() == s2); System.out.println(s1.equals(" AB".trim())); System.out.println("AB".equals("ab")); } Sing pisanan sing nulis kabeh jawaban kanthi bener (sing ora bisa) entuk cookie lan plus kanggo karma :)
