char 和String的转换问题？
下面程序的结果为？public class String_to_char { public static void main(String[] args) { String s = "hello"; char ch[] = s.toCharArray(); String s1 = new String(ch); System.out.println("\n"+s1); if(s1.equals(s)){ System.out.print(true); }else System.out.print(false); if(s.equals(ch)){ System.out.print("true"); }else{ System.out.print("false"); } char a1[] ={'h','e','l','l','o'}; if(ch.equals(a1)){ System.out.print("true"); }else{ System.out.print("false"); } }}
