Answer:
Three point lighting.
Explanation:
Write a while loop that replaces every occurrence of “cat” in the message with “dog” using the indexOf and substring methods.
Given:
public class ChallengeReplace
{
public static void main(String[] args)
{
String message = "I love cats! I have a cat named Coco. My cat's very smart!";
// Write a loop here that replaces every occurrence of "cat"
// in the message with "dog", using indexOf and substring.
}
}
Answer:
Complete the program using:
int index = message.indexOf("cat");
while(index != -1){
message = message.replace("cat","dog");
index = message.indexOf("cat");
}
System.out.print(message);
}
}
Explanation:
The line gets the index of string "cat"
int index = message.indexOf("cat");
The following operation is repeated until all occurrence of "cat"s has been replaced with dog
while(index != -1){
message = message.replace("cat","dog");
index = message.indexOf("cat");
}
This prints the new string
System.out.print(message);
}
}
The program illustrates the use of loops.
Loops are used to perform repetitive and iterative operations.
The code segment where comments are used to explain each line, is as follows:
//This gets the index of "cat" in the string message
int index = message.indexOf("cat");
//The following loop is repeated, until there is no occurrence of "cat" in the string
while(index != -1){
//This replaces "cat" with "dog"
message = message.replace("cat","dog");
//This gets another index of "cat" in the string message
index = message.indexOf("cat");
}
//This prints the new string
System.out.print(message);
}
}
At the end of the loop, all occurrence of "cat" are replaced with "dog".

Answer:
1. Which of the following is not the name of a Java wrapper class from the Java API?
A. Byte
B. Int
C. Long
D. Boolean
Int is not a wrapper class
Byte is the wrapper class of byte, Int is not a wrapper class and is a primitive data type, Long is a wrapper class of long, Boolean is a wrapper class for boolean. Hence Int is the correct answer and its wrapper class is Integer.
2. Which of the following statements will cause a compiler error?
A. Integer i = new integer ( ) ;
B. Integer j = new integer ("5") ;
C. Integer k = Integer.valueOf ("5");
D. int m = Integer.pareseInt ("5");
“I” in integer in A and B must be in capital.

A. The double value held in j is less than the value held inside k.
B. The difference between values held in j and k is 1.
C. The double values held inside j and k are both positive.
D. The double value held inside j is greater than the value held inside k.
Compareto return 1 if first value is greater than with what it is compared.
4. What is a radix as used in the method parseInt (String s, int radix) from the integer class?
A. A numeric base 2 such as for binary or 16 for hexadecimal.
B. The number of characters in the string that represent integers.
C. The Unicode character code to be used when parsing the string.
D. The number of times the string should be repeated before being converted to an int.
The radix value is 10 for decimal, 2 for binary and 16 for hexadecimal. Radix is the base or number of unique digits.
5. Which of the following is a static method of the integer class?
A. intValue ( )
B. parseInt ( )
C. toString ( )
D. compareTo ( )
ParseInt() is a static method of the integer class, and rest are non static methods.
6. Which of the following statements will cause a compiler error?
A. Double a = new Double (10.6) + 3;
B. Integer b = 0;
C. Double c = 0;
D. int d = new Integer (7) ;
In A and C data type does not matches like Double c=0 means Double c=new int(0) which is never true.

A. Boolean a = false
B. Integer b = new integer (9);
C. double x = 3.0;
Double c = x;

Steve Jobs described early computers as “the most remarkable tool that we’ve ever come up with..it’s equivalent of a bicycle for our minds.” Would you describe smartphones as a bicycle for our minds?
Answer:
Here is my stance on the phone issue and a quote from Steve himself.
"I think one of the things that really separates us from the high primates is that we’re tool builders. I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. And, humans came in with a rather unimpressive showing, about a third of the way down the list. It was not too proud a showing for the crown of creation. So, that didn’t look so good. But, then somebody at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle. And, a man on a bicycle, a human on a bicycle, blew the condor away, completely off the top of the charts.
And that’s what a computer is to me. What a computer is to me is it’s the most remarkable tool that we’ve ever come up with, and it’s the equivalent of a bicycle for our minds."
Explanation:
Like anything smartphones, computers, and television can be the junk-food equivalent of our minds or the inspiration to better yourself with knowledge and creativity. To me its like a bicycle in that are you riding the bicycle to healthfoods or mcdonalds. Its the freedom of the transportation of knowledge that can be so life-changing and so life-threating at the same time.
I would not think of smartphones as a bicycle for our minds as they do not run on how my mind functions.
What are people view on the quote above?Some people do believe that the statement is true. They think also that smartphones and tablets can be a source of big distraction if not handled well.
Smartphones are a good learning tools, or they can be bicycles for our minds only when they are used by a skillful person.
