1. Write an expression whose value is the result of converting the str value associated with s to an int value. So if s were ass
ociated with "41" then the resulting int would be 41.2. Write an expression whose value is the last character in the str associated with s.
3. Given variables first and last, each of which is associated with a str, representing a first and a last name, respectively. Write an expression whose value is a str that is a full name of the form "Last, First". So, if first were associated with "alan" and last with "turing", then your expression would be "Turing,Alan". (Note the capitalization! Note: no spaces!) And if first and last were "Florean" and "fortescue" respectively, then your expression’s value would be "Fortescue,Florean".
4. Write an expression whose value is the result of converting the int value associated with x to a str. So if 582 was the int associated with x you would be converting it to the str "582".
5. Write an expression whose value is the str consisting of all the characters (starting with the sixth) of the str associated with s.

Answer:
The solution or expression for each part is given below:
- int(s)
- s[len(s)-1]
- last.capitalize()+','+first.capitalize()
- str(x)
- s[5:]

Answer:
Follows are the code to this question:
import java.util.*;//import packae for user-input
public class Main//defining a class Main
{
public String[] getArray(int numString)//defining a method getArray
{
String[] name=new String[numString];//defining array of String values
Scanner in = new Scanner(System.in);// creating scanner class object for input values from user-end
for(int i=0;i<numString;i++)//defining for loop for input multiple values
{
System.out.print("Enter String Value :");//print message
name[i]=in.nextLine();//input values
}
return name;//return array values
}
public String getLongestString(String[] sArray)//defining a method getLongestString
{
int m=0,mi=0; //defining integer variables
for(int i=0;i<sArray.length;i++)//defining for loop for check the longest value in array
{
if(m<sArray[i].length())//defining if block that checks m varaible value greater then sArray length
{
m=sArray[i].length();//use m to hold sArray length
mi=i;//use max_index to hold i that is loop value
}
}
return sArray[mi];//return Longest value
}
public static void main(String[] args)//defining main method
{
Main s=new Main();//Creating object of main class
String[] n;//defining string variable n
n=s.getArray(5);//use n varaible to call getArray method and store its value
System.out.println("Longest value is: "+s.getLongestString(n));//use print method to call getLongestString method
}
}
Output:
please find attached file.
Explanation:
In the given java program code, inside the main class two method that is "getArray and getLongestString", is defined, in which the "getArray" method uses an integer variable in its parameter and inside the method, an array is defined that use a scanner class for input array value.
- In the "getLongestString" pass as a parameter and inside the method, two integer variable "m and mi" is defined that use in the loop to return the longest string value.
- In the class main method is to define that creates a class object and call the above method and use the print method to return its value.
