12345
2345
345
45
5

String base = "012345";

int count = 0;
while (count <= 5)
{
  String tmp = ______________;
System.out.println(tmp);
count++;   
}

a) base.substring(count,6)

b) base.substring(1,count+1)

c) base.substring(0, count)

D)base.substring(count+1)

e)  base.substring(count)

Answer 1

Given code:

public class Missing {
   public static void main(String[] args) {
       String base = "012345";
       int count = 0;
       while(count <= 5) {
           String tmp = ------------------------;
           System.out.println(tmp);
           count++;
       }
   }
}
Options:

• a) base.substring(count,6)

• b) base.substring(1,count+1)

• c) base.substring(0, count)

• D)base.substring(count+1)

• e)  base.substring(count)

Answer: Option (a) and (e) gives the same result.

CODE:

public class Missing {
   public static void main(String[] args) {
       String base = "012345";
       int count = 0;
       while(count <= 5) {
           String tmp = base.substring(count,6);
           System.out.println(tmp);
           count++;
       }
   }
}
