What is the difference between (IF instructions & WHILE instructions )

Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.

Just a quick question, how do you set something == to char and int in an if statement (java)
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() 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"
Your program must define the method:
public String checkCharacter(String word, int index)
this is what i got to but im stuck on how to find out if its a char or int
public class TollCalculation {
public double calcToll(int hour, boolean isMorning, boolean isWeekend) {
Scanner scnr = new Scanner(System.in);
int timeHour; // Time of travel hour (24 hour format)
int timeMinute; // Time of travel minute
int inputColon; // Used to read time format
String userInput; // User specified time
double tollAmount;
}
public static void main(String[] args) {
TollCalculation tollObj = new TollCalculation();
// Test the three samples from the specification.
System.out.println(tollObj.calcToll(7, true, false));
System.out.println(tollObj.calcToll(1, false, false));
System.out.println(tollObj.calcToll(3, true, true));
}
}
This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.

Describe the two problems that appear in the construction of large programs that led to the development of encapsulation constructs.
Two problems that can lead to the development of encapsulation constructs when creating large programs are the complexity of data and the lack of security in sensitive data.
We can arrive at this answer because:
Encapsulation constructs are designed to prevent data from being invaded by unauthorized person.These constructions must be done without causing inconsistencies in the system, interfering with codes, and increasing the complexity of data. For this reason, large programs that present high complexity and difficult codes, demand the use of encapsulation constructs, so that their data does not become more complex.Encapsulation constructs are also necessary when there are flaws in data security and it is not possible to keep them away from the attack by intruders.Although there are other ways to accomplish these goals, encapsulation constructs are widely used because of their simplicity and efficiency.
