Answer:
The method is as follows:
public static int lastIndexOf(int [] numbers, int num){
int lastIndex = numbers[0];
for(int i =0; i<numbers.length;i+=num){
lastIndex = numbers[i];
}
return lastIndex;
}
Explanation:
This defines the method
public static int lastIndexOf(int [] numbers, int num){
This initializes the lastIndex to the first element of the array
int lastIndex = numbers[0];
This iterates through every "num" element of the array
for(int i =0; i<numbers.length;i+=num){
This gets the current index... until the last
lastIndex = numbers[i]; }
This returns the last
return lastIndex; }
Answer:
// here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare variable
double caffeine;
// scanner object to read input from user
Scanner scr=new Scanner(System.in);
System.out.print("Enter the initial amount of caffeine:");
// read the initial amount of caffeine
caffeine=scr.nextDouble();
// calculate amount of caffeine after 6,12,18 hours
for(int i=1;i<=3;i++)
{
System.out.println("After "+ i*6+" hours:"+(caffeine/2)+" mg");
// update the caffeine after every 6 hours
caffeine=caffeine/2;
}
}catch(Exception ex){
return;}
}
}
Explanation:
Create a variable "caffeine" to store the initial amount of caffeine given by user. Run a loop for three time, it will calculate the amount of caffeine left after every 6 hours.First it will give the amount of caffeine left after 6 hours, then caffeine left after 12 hours and in last caffeine after 18 hours.
Output:
Enter the initial amount of caffeine:100
After6 hours:50.0 mg
After12 hours:25.0 mg
After18 hours:12.5 mg

Answer:
B) A block of statement that might cause an exception.
Explanation:
Exception handling is a good programming technique that prevents our program from crashing when an exception occurs during execution. The try clause is used with a catch to handle any exception that might occur, so whenever a statement that might cause an exception is to be used, this should be contained in a try statement block of code.
