帮我看看这个程序，在线等！！！急

[ldshalh520]

这个程序是要统计排序 "Language Specification"

要求输出:a:3,c:2,e:2…
aaaccee

我现在已经做到了 a:3,c:2,e:2...

现在不知道怎么输出下面 aaaccee


/*
* Test

proc(str);

List Test = get (Num);
Test = sort(Test);
out(Test,Num);

}

}

}

晕，我上面给你的就是思路啊，你完全可以在你的程序基础上实现啊

[ldshalh520]

我不会阿，请你帮帮我啊~

[imA]

唉

package cn.com.shdb.jt;

import java.util.ArrayList;
import java.util.Enumeration;
import java.util.Hashtable;
import java.util.List;

public class Test {
	public static void main(String[] args) {
		String str = "Language   Specification";
		str = str.replaceAll("   ", "");
		proc(str);
	}

	public static void proc(String name) {
		Hashtable Num = add(name);
		List Test = get(Num);
		Test = sort(Test);
		out(Test, Num);

	}

	public static Hashtable add(String name) {

		Hashtable Num = new Hashtable();

		for (int i = 0; i < name.length(); i++) {
			String bata = name.substring(i, i + 1).toLowerCase();

			if (Num.containsKey(bata)) {
				int out = ((Integer) Num.get(bata)).intValue() + 1;
				Num.put(bata, out);
			}

			else {
				Num.put(bata, 1);
			}

		}
		return Num;
	}

	public static List get(Hashtable Num) {
		List Test = new ArrayList();
		for (Enumeration e = Num.keys(); e.hasMoreElements();) {
			Test.add(e.nextElement());
		}
		return Test;
	}

	public static List sort(List Test) {

		int k;
		int j;
		String temp = new String();

		for (int i = 0; i < Test.size(); i++) {
			for (j = i, k = i; j < Test.size(); j++) {
				String A = (String) Test.get(j);
				String B = (String) Test.get(k);
				if (A.compareTo(B) < 0)
					k = j;
			}
			temp = (String) Test.get(i);
			Test.set(i, (String) Test.get(k));
			Test.set(k, temp);
		}
		return Test;
	}

	public static void out(List testGet, Hashtable numGet) {
		StringBuffer sb=new StringBuffer();
		for (int i = 0; i < testGet.size(); i++) {
			int count=((Integer)numGet.get(testGet.get(i))).intValue();
			System.out.print(testGet.get(i) + ":"+ count + ",");
			for(int j=0;j<count;j++)
				sb.append(testGet.get(i));
		}
		System.out.println();
		System.out.println(sb.toString());
		
	}
}

public static void out(List testGet,Hashtable numGet) {
for (int i=0;i <testGet.size() ;i++ ) {
System.out.print((String)testGet.get(i)+":"
+ numGet.get(testGet.get(i)).toString()+",");

}
for(int i=0;i<testGet.size();i++)
{
String c=(String)testGet.get(i);
for(int j=0;j<((Integer)numGet.get(c)).intValue();j++)
{
System.out.print(c);
}
}

}
测试输出结果:a:3,c:2,e:2,f:1,g:2,i:3,l:1,n:2,o:1,p:1,s:1,t:1,u:1,aaacceefggiiilnnopstu
我也是菜鸟 自己照资料改的

[liuyi900]

楼上大哥的代码真严谨

[liuyi900]

说错了 我楼上的大哥 IMA的 学习中

[imA]

public class Test {
	
	/**
	 * Method main
	 *
	 *
	 * @param args
	 *
	 */
	public static void main(String[] args) {
		// TODO: Add your code here
		String s="Language   Specification";
		java.util.Map stat=new java.util.HashMap();
		char[] cs=s.toCharArray();
		for(int i=0;i<cs.length;i++){
			if(cs[i]!=' '){
				Integer count=(Integer)stat.get(new Character(cs[i]));
				if(count!=null){
					count++;
					stat.put(new Character(cs[i]),count);
				}
				else{
					stat.put(new Character(cs[i]),new Integer(1));
				}
			}
		}
		java.util.Set keyset=stat.keySet();
		Object[] keyarray=keyset.toArray();
		java.util.Arrays.sort(keyarray);
		
		StringBuffer sb=new StringBuffer();
		for(int i=0;i<keyarray.length;i++){
			int count=((Integer)stat.get(keyarray[i])).intValue();
			System.out.print(keyarray[i]+":"+count+",");
			for(int j=0;j<count;j++)
				sb.append(keyarray[i]);	
		}
		System.out.println();
		System.out.println(sb.toString());
	}	
}

我只想在我的程序上面做~
