limitations of systems analysis and design
Answer:
Explanation:
Although System analysis offers an extensive range of benefits it might also have some disadvantages. One of the main disadvantages which is mostly overlooked is the risk of too much analysing which may be costly and time consuming. It is therefore part of the analyst's job to find the right balance.Could someone write the code for this in java? I cannot use java.util random(but i can use scanner). also, i cannot use switch or case.
Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Add statements to the program as indicated by the comments so that the program asks the user to enter a play, generates a random play for the computer, compares them and announces the winner (and why). For example, one run of your program might look like this:
Enter your play: R, P, or S
r
Computer play is S
Rock crushes scissors, you win!
Note that the user should be able to enter either upper or lower case r, p, and s. Add a loop to make sure the user only enters an R, P, or S. The user's play is stored as a string to make it easy to convert whatever is entered to upper case. Use if statements to convert the randomly generated integer for the computer's play to a string.
public class Rock
{
public static void main(String[] args)
{
String personPlay; //User's play -- "R", "P", or "S"
String computerPlay; //Computer's play -- "R", "P", or "S"
int computerInt; //Randomly generated number used to determine
//computer's play
// Add the code for each action beneath the comment. // more than one line may be needed in some cases // Get player's play -- note that this is stored as a string
// Make player's play uppercase for ease of comparison
// Generate computer's play (0,1,2) – use (int) (Math.random() * 3) to
// generate a random play
// Translate computer's randomly generated play to string // using mutually exclusive conditional statements
// Print computer's play
// See who won. Use nested ifs instead of &&.
}
}
People hardly ever play Rock, Paper, Scissors one game at a time. They play matches that are best 2 out of 3, best 3 out of 5, etc. Change your program to prompt the user for the odd number of games they want to play and use a loop to make sure it is an odd number. Then, add a loop to your program to play the game multiple times. Keep track of who wins, and make sure the loop stops when either the computer or the user has accumulated enough wins. Ties do not count in either the game total or the win totals – so a best 2 out of 3 match requires 3 games to be played where someone wins 2 times.
Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Open it and save it to your directory.
Add statements to the program as indicated by the comments so that the program asks the user to enter a play,
generates a random play for the computer, compares them and announces the winner (and why). For example, one run
of your program might look like this:
$ java Rock
Enter your play: R, P, or S
r
Computer play is S
Rock crushes scissors, you win!
Note that the user should be able to enter either upper or lower case r, p, and s. The user's play is stored as a
string to make it easy to convert whatever is entered to upper case. Use a switch statement to convert the randomly
generated integer for the computer's play to a string.*/

Fun with Characters
Complete the checkCharacter() method which has 2 parameters: A String, and a specified index (int). The method checks the character at the specified index of the String parameter and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
CODE:
public class LabProgram {
public static String checkCharacter(String inputString, int index){
/* Type your code here. */
}
public static void main(String[] args) {
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
System.out.println(checkCharacter("happy birthday!", 14));
}
}
The program is an illustration of conditional statements.
Conditional statements are statements whose execution is dependent on the truth value of the condition.
The checkCharacter() method in Java, where comments are used to explain each line is as follows:
//This defines the checkCharacter() method
public static String checkCharacter(String inputString, int index){
//This checks if the character at the index, is a digit
if(Character.isDigit(inputString.charAt(index))){
//If yes, it returns "Digit"
return "Character "+inputString.charAt(index)+" is a digit";
}
//This checks if the character at the index, is a letter
else if(Character.isLetter(inputString.charAt(index))){
//If yes, it returns "letter"
return "Character "+inputString.charAt(index)+" is a Letter";
}
//This checks if the character at the index, is a white space
else if(inputString.charAt(index) ==' '){
//If yes, it returns "white space"
return "Character "+inputString.charAt(index)+" is a white space";
}
#If all the above conditions are false
else{
//If yes, it returns "unknown character"
return "Character "+inputString.charAt(index)+" is an unknown character";
}
}
The string to return depends on the character at the index.

What is a random integer in programming?This is a random sequence of integers that may be used to imitate things like shuffling a deck of cards or creating distinct behaviors every time a program runs. The RND function in BASIC generates random numbers. This yields a value between 0 and 1.
Random number creation is a technique that generates a series of numbers or symbols that cannot be realistically anticipated better than by random chance, generally using a random number generator (RNG).
