简单的方法来反转字符串

Question

没有经过char序列,有任何方法可以String在Java中反转

Answer 1

试试这个,

String s = "responses";
StringBuilder builder = new StringBuilder(s);
System.out.println(builder.reverse());

Answer 2

您可以使用以下StringBuilder#reverse()方法:

String reverse = new StringBuilder(originalString).reverse().toString();

Answer 3

使用StringBuilder's或StringBuffer's方法......reverse()

 public class StringReverse
{
  public static void main(String[] args)
  {
  String string=args[0];
  String reverse = new StringBuffer(string).reverse().toString();
  System.out.println("\nString before reverse: "+string);
  System.out.println("String after reverse: "+reverse);
  } 
} 

StringBuffer是线程安全的,因为那里StringBuilder是不是线程安全的 ..... StringBuilder 从Java 1.5中引入的,因为做这些操作变得更快,其不具有任何并发担心....

Answer 4

尝试reverse()方法:

StringBuilder stringName = new StringBuilder();
String reverse = stringName.reverse().toString();
