helloworld.java

常用的java控件使用实例源代码

public class HelloWorld{
public static void main(String[] args) { 
        String string="TEST2008"; 
        String returnString = ""; 
  try { 
char[] charAry = new char[string.length()]; 
for (int i = 0; i < string.length(); i++) { 
charAry[i] = (char) string.charAt(i); 
returnString = returnString + Integer.toString(charAry[i], 2); 
} 
} catch (Exception e) { 
  e.printStackTrace(); 
} 
System.out.println(returnString); 

}
}
