1. Create a toString method that takes no parameters and returns a String. This method should use a
loop to build and returns a String with the contents of your character array.
Solution
StringTest.java
import java.util.Scanner;
public class StringTest {
/**
* @param args
*/
static char ch[];
public static void main(String[] args) {
// TODO Auto-generated method stub
new StringTest();
}
public StringTest(){
Scanner scan = new Scanner(System.in);
System.out.println("Enter the string :");
String s = scan.nextLine();
setString(s);
System.out.println("The Entered String is : "+toString());
}
public void setString(String s){
ch = new char[s.length()];
for(int i=0; i<s.length(); i++){
ch[i] = s.charAt(i);
}
int length = ch.length;
System.out.println("The length of char array is :"+length);
}
public String toString(){

2. String s = "";
for(int i=0; i<ch.length; i++){
s = s + ch[i];
}
return s;
}
}
Output:
Enter the string :
Hi, How are you
The length of char array is :15
The Entered String is : Hi, How are you
