Program: How to copy vector to array?


Description:

You can copy all elements of a vector object to an array. By passing an array object to copyInto() method, you can copy content of a vector object to an array.


Code:
package com.java2novice.vector;

import java.util.Vector;

public class MyVectorArrayCopy {

	public static void main(String a[]){
		Vector<String> vct = new Vector<String>();
		vct.add("First");
		vct.add("Second");
		vct.add("Third");
		vct.add("Random");
		System.out.println("Actual vector:"+vct);
		String[] copyArr = new String[vct.size()];
		vct.copyInto(copyArr);
		System.out.println("Copied Array content:");
		for(String str:copyArr){
			System.out.println(str);
		}
	}
}

Output:
Actual vector:[First, Second, Third, Random]
Copied Array content:
First
Second
Third

ServletOuptputStream Vs PrintWriter
ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response's character encoding has not been specified then it does default character encoding.
