piglatin.java

JAVA编程的很好的实例啊

import java.io.*;


public class PigLatin
{
	static BufferedReader keyboard =new BufferedReader(new InputStreamReader(System.in));
	
	public static Boolean isVowel(char ch)
	{

			case 'U':case 'Y':
			case 'a':case 'e':
			case 'i':case 'o':
			case 'u':case 'y': return true;
			default:return false;
		}
	}
	
	public static String rotate(String pStr)
	{
		int len=pStr.length();
		String rStr;
		rStr=pStr.substring(1,len)+pStr.charAt(0);
		return rStr;
	}
	
	public static String pigLatinString(String pStr)
	{

		boolean foundVowel;
		
		int counter;
		if(isVowel(pStr.charAt(0)))
