java写的StringList类

Delphi的StringList类真好用啊 试着用Java写了一个

package com.zhao_yi.sysutils.classes;

import java.util.List;
import java.util.ArrayList;
import java.util.StringTokenizer;
import com.zhao_yi.sysutils.SysUtil;
import com.zhao_yi.sysutils.*;
import java.util.Arrays;
import java.util.*;

public class StringList {

public StringList() {
}

public String[] getStrings() {
return (String[])strings.toArray(new String[strings.size()]);
}

public void setStrings(String[] array){
strings = null; objects=null;
strings = new ArrayList(Arrays.asList(array));
objects = new ArrayList(array.length);
}

private void rangeCheck(int Index) throws IndexOutOfBoundsException {
if ((Index < 0) || (Index >= getCount()))
throw new IndexOutOfBoundsException();
}

public int getCount() {
return strings.size();
}

public String Get(int Index){
return (String) strings.get(Index);
}

public int Find(String S) {
int I, L, H, C;
L = 0;
H = getCount() - 1;
while (L <= H) {
I = (L H) / 2;

if (C < 0)
L = I 1;
else {

if (C == 0)
L = I;
}
}
return L;
}

public int AddObject(String S, Object AObject) {
int Result = -1;

}

}

}

public void AddStrings(String[] Strings) {
for (int i = 0; i < Strings.length; i )

}

public void Clear() {
strings.clear();
objects.clear();
}

public void Delete(int Index){
strings.remove(Index);
objects.remove(Index);
}

public void InsertItem(int Index, String S, Object AObject) {

}

throw new IllegalStateException("list sorted!");
else

}

objects.set(Index, AObject);
}

public void Exchange(int Index1, int Index2) {
Object temp = null;
temp = strings.get(Index1);
strings.set(Index1, strings.get(Index2));
strings.set(Index2, temp);
temp = objects.get(Index1);
objects.set(Index1, objects.get(Index2));
objects.set(Index2, temp);
}

public void QuickSort(int L, int R) {
if (L < R) {
int i = L;
int j = R;
String S = Get(L);
while (i < j) {
while (SysUtil.CompareStrings(Get(i), S) <= 0)
i ;
while (SysUtil.CompareStrings(Get(j), S) > 0)
j--;
if (i < j)
Exchange(i, j);
}
Exchange(i, L);
if (L < j)
QuickSort(L, j);
if (i < R)
QuickSort(i, R);
}
}

public void SetSorted(boolean value) {
if (value != sorted) {
if (value)
QuickSort(0, getCount() - 1);
sorted = value;
}
}

public int IndexOf(String S) {
return strings.indexOf(S);
}

public String getTextStr() {
StringBuffer Result = new StringBuffer();
for (int i = 0; i < strings.size(); i ) {
Result.append(Get(i));
Result.append(Systems.lineseparator);
}
return Result.toString();
}

public void setTextStr(String value) {
Clear();
StringTokenizer tokenizer = new StringTokenizer(value, Systems.lineseparator);
while (tokenizer.hasMoreTokens())
Add(tokenizer.nextToken());
}

}
