三、有下列 JAVA 程式片段,請寫出執行結果。(20 分) String s4 = new String(“restful”) ; String s5 = new String(“restful”) ; String s6 = new String(“peaceful”) ; String s7 = s4 ; String s8 = “restful” ; String s9 = “restful” ; System.out.println(s4.equals(s5)) ; System.out.println(s4.equals(s6)) ; System.out.println(s4 == s5) ; System.out.println(s4 == s7) ; System.out.println(s4 == s8) ; System.out.println(s8 == s9) ;
