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 an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
Answer:
public static void print_popcorn_time(int bag_ounces){
if(bag_ounces<3){
System.out.println("Too Small");
}
else if(bag_ounces>10){
System.out.println("Too Large");
}
else{
bag_ounces*=6;
System.out.println(bag_ounces+" seconds");
}
}
Explanation:
Using Java prograamming Language.
The Method (function) print_popcorn_time is defined to accept a single parameter of type int
Using if...else if ....else statements it prints the expected output given in the question
A complete java program calling the method is given below
public class num6 {
public static void main(String[] args) {
int bagOunces = 7;
print_popcorn_time(bagOunces);
}
public static void print_popcorn_time(int bag_ounces){
if(bag_ounces<3){
System.out.println("Too Small");
}
else if(bag_ounces>10){
System.out.println("Too Large");
}
else{
bag_ounces*=6;
System.out.println(bag_ounces+" seconds");
}
}
}

Answer:
Answered below
Explanation:
//Program is written in Python programming //language.
number_of_trees = int(input ("Enter number of trees purchased: "))
height_of_trees = float(input("Enter height of trees: "))
delivery_status = input("Do you want trees delivered? enter yes or no ")
price_of_two_meters = 20
total_price = number_of_trees * price_of_two_meters
//Invoice
print (number_of_trees)
print(height_of_trees)
print (total_price)
print (delivery_status)
On a printed circuit board, electronic parts will be mounted from the substrate side of the board. The leads jab through the substrate and the copper sheeting that has been carved. The leads are then soldered to the copper.
I hope the answer will help you.
