Output string in reverse order


  
  public static void main(String[] args) {
		  	String str = "!xc doog";
		  	String[] content = str.split(" ");
		  	String result = "";
		  	for (String s : content) {
				result +=revertString(s);
			}
		  	System.out.println(result);
	    }
	     
	    public static String revertString(String str) {
	        if (str == null) {
	            return null;
	        }
	        char[] chars = str.toCharArray();
	        int len = chars.length;
	        int half = len/2;
	        char first;
	        for (int i = 0; i < half; i++) {
				first = chars[i];
				chars[i] = chars[len-1-i];
				chars[len-1-i] = first;
			}
	        return new String(chars);
	    }
Output
result ：cx!good
principle ： Split the strings that need to be in reverse order in half , Then the first character and the last character exchange positions , Circular convenient sequential exchange , Finally, we get the result .
