Answer: Distillation and Landfill
Explanation:
Distillation is the old method of water purification, these process involves the separation of compounds or components of a mixture based on their different boiling points. Today we have advanced method of seperation, although Distillation is still being used.
Land fill is one of the oldest form of waste disposal, these method involves digging up a large land mass(depending on the waste to be disposed) and dumping the water into the dugged land mass, then cover it up with the sand that was dugged out. Today, they are more advanced ways to handle wastes such as incinerator.
Answer:
public class Pyramid {
public static void main(String[] args) {
int h = 7;
System.out.println("Pattern A");
for(int i = 1; i <= h; ++i)
{
for(int j = 1; j <= i; ++j) {
System.out.print("+");
}
System.out.println();
}
System.out.println();
System.out.println("Pattern B");
for (int i = 1; i<=h; ++i)
{
for(int j = h; j >=i; --j){
System.out.print("+");
}
System.out.println();
}
}
}
Explanation:
- The trick in this code is using a nested for loop
- The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
- The inner for loop which prints the (+) sign runs from j = 0 to j<=i
- It prints the + using the print() function and not println()
- In the pattern B the loop is reversed to start from i = height
