What is the output of this program?
import java.io.*;
public class Chararrayinput_Example
{
public static void main(String[] args)
{
String object = "pqrst";
int length = object.length();
char p[] = new char[length];
object.getChars(0, length, p, 0);
CharArrayReader input1 = new CharArrayReader(p);
CharArrayReader input2 = new CharArrayReader(p, 1, 4);
int K;
int L;
try
{
while ((K = input1.read()) == (L = input2.read()))
{
System.out.print((char)K);
}
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
-
- pqrst
- pqr
- rst
- pqrs
- None of these
Correct Option: E
No output is printed. CharArrayReader object input1 contains string “pqrst” whereas object input2 contains string “qrst”, when while((K=input1.read())==(L=input2.read())) is executed the starting character of each object is compared since they are unequal control comes out of loop and nothing is printed on the screen.
