Explanation of Solution
Given code:
The below code is used to print the values from 1 to 4 using “for” loop.
//Define the Main class
public class Main
{
//Define main method
public static void main(String[] args)

for ( int i =0; i <= n; i++ )
{
System.out.println( "The number is " + i );
if ( i == n )
i = i – n;
}
identify the type of error in the above code and give brief explanation to it
2- Trace the following code and write the output:
class Test1 {
Test1(int x)
{
System.out.println("Test Calls " + x);
class
Test2 {
Testi t1 = new Test1(10);
Test2(int i) { t1 = new Test1(i); }
public static void main(String[]
args)
{
Test2 t2 = new Test2(5);
Consider the following code:
public static void test_a(int n) { System.out.println(n + " "); if (n>0) test_a(n-2); }What is printed by the call test_a(6)?

The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…arrow_forward

We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…arrow_forward
