正确例题 public class Test { public static void main(String[] args) { String s1 = "abcdefghijklmnopqrstuvwxyz"; String s2 = "abc"; if(s1.contains(s2)){ System.out.println("s1包含了s2"); System.out.println(s2); }else{ System.out.println("s1不包含s2"); } } }
正确例题 import java.util.*; public class Ha{ public static void main(String[] args) { String a[]={"a","b","c"}; String b[]={"a","b","c"}; System.out.println(Arrays.equals(a, b)); } }
正确例题 import java.util.*; public class Ha{ public static void main(String[] args) { String str1= "你好"; String str2= "你号"; if (str1.equals(str2)) { System.out.println("相等"); }else{ System.out.println("不相等"); } } }
能通过编译 import java.util.*; public class Ha{ public static void main(String[] args) { String a[]={"a","b","c"}; String b[]={"a","b","c"}; if (a.equals(b)) { System.out.println("相等"); }else{ System.out.println("不相等"); } } }
