Answer:

The memory with variable names str1, str2, and str3 all have equal and the same value after the first if-statement.

Explanation:

The str1 was first assigned a null value while the str2 and str3 were assigned the string value "Karen" with the String class and directly respectively. On the first if-statement, the condition checks if the str1 is null and assigns the value of the variable str2 to str1, then the other conditional statement compares the values of all the string variables.

Answer:

Explanation:

It knows how to remember data and where to find that data. In other words, it knows how the raw memory works. (RAM).

It understands how to make a program run within the confines of its logical steps in an order that makes the program work the way the user intends.

It can be made to display short cuts, or any icon or picture (not an obvious talent).

It can search for unwanted intruders like ads or viruses.

It can can time events even to the point of getting your coffee ready for you with the proper add on.

1. Print out the string length of s1 2. Loop through characters in s2 with charAt() and display reversed string 3. Compare s2, s
konstantin123 [22]

Answer:

See explaination

Explanation:

public class StringLab9 {

public static void main(String args[]) {

char charArray[] = { 'C', 'O', 'S', 'C', ' ', '3', '3', '1', '7', ' ', 'O', 'O', ' ', 'C', 'l', 'a', 's', 's' };

String s1 = new String("Objected oriented programming language!");

String s2 = "COSC 3317 OO class class";

String s3 = new String(charArray);

// To do 1: print out the string length of s1

System.out.println(s1.length());

// To do 2: loop through characters in s2 with charAt and display reversed

// string

for (int i = s2.length() - 1; i >= 0; --i)

System.out.print(s2.charAt(i));

System.out.println();

// To do 3: compare s2, s3 with compareTo(), print out which string (s2 or s3)

// is

// greater than which string (s2 or s3), or equal, print the result out

if (s2.compareTo(s3) == 0)

System.out.println("They are equal");

else if (s2.compareTo(s3) > 0)

System.out.println("s2 is greater");

else

System.out.println("s3 is greater");

// To do 4: Use the regionMatches to compare s2 and s3 with case sensitivity of

// the first 8 characters.

// and print out the result (match or not) .

if (s2.substring(0, 8).compareTo(s3.substring(0, 8)) == 0)

System.out.println("They matched");

else

System.out.println("They DONT match");

// To do 5: Find the location of the first character 'g' in s1, print it out

int i;

for (i = 0; i < s2.length(); ++i)

if(s2.charAt(i)=='g')

break;

System.out.println("'g' is present at index " + i);

// To do 6: Find the last location of the substring "class" from s2, print it

// out

int index = 0, ans = 0;

String test = s2;

while (index != -1) {

ans = ans + index;

index = test.indexOf("class");

test = test.substring(index + 1, test.length());

}

System.out.println("Last location of class in s2 is: " + (ans + 1));

// To do 7: Extract a substring from index 4 up to, but not including 8 from

// s3, print it out

System.out.println(s3.substring(4, 8));

} // end main

} // end class StringLab9

ch4aika [34]

The example where the alarm of the house set up, delivery updated should be provided, etc should represent the function example of the artificial intelligence.

The following information related to artificial intelligence is:

  • It refers to the human intelligence where the machines could be treated as humans and according to this, the actions should be mimic.
  • It should be used for any kind of machine where the traits should be associated along with the mind of the human-like for learning & problem-solving purpose.

Therefore we can conclude that The example where the alarm of the house set up, delivery updated should be provided, etc should represent the function example of the artificial intelligence.
