JAVA高手请进！

public class Java_1 {
public static void main(String args[])
{
final char chrA='A';
char chrDisplay;

for(int i=0;i<='Z';i++)
{
//************Found************
chrDisplay=______(chrA+i);
System.out.print(chrDisplay) ;
}
}
}

你的程序我给你改了一下：
public class Java_1 {
public static void main(String args[])
{
final char chrA='A';
char chrDisplay;
for(int i=0;i<26;i++)
{
//************Found************
chrDisplay=(char)(chrA+i);
System.out.print(chrDisplay) ;
}
}
}

import java.util.*; class condemo { public static void main(string[] args) { collection c1 = new arraylist(25); c1.add(new string("one")); c1.add(new string("two")); string s = "three"; c1.add(s); for (int i = 0; i < c1.size(); i++) system.out.println(c1.toarray()[i]); }} 把system.out.println(c1.get(i));改为system.out.println(c1.toarray()[i]);
