Java use for loop (nested for loop) if/else possible
on blue J.
(row *col)%2 for 0's and 1's.
Please find the answer below:
I have created a separate method which prints design according to the argument passed.
I have mentioned all the details in the comment.
Please change class name according to your requirement.
import java.util.Scanner;
public class Table {
public static int SIZE = 7;
//method to print different design as per requirement
public static void print_design(int d,int n){
switch (d){
case 1 :
System.out.print(" ");
break;
case 2:
System.out.print("------- ");
break;
case 3:
System.out.print(" |");
break;
case 4:
System.out.print(" |");
break;
case 5:
System.out.print(" "+n+" |");
break;
case 6:
System.out.print(" -------|");
break;
case 7:
System.out.print("-------|");
break;
case 8:
System.out.print("| |");
break;
case 9:
System.out.print(" |");
break;
case 10:
System.out.print("| "+n+" |");
break;
case 11:
System.out.print("|-------|");
break;
}
}
//print the last line of each row
public static void print_row_label(int row){
for(int i=0;i<=SIZE;i++){
//if it's first row
if(i==0 && row==0){
print_design(6,-1);
}
//for each row except 0th one
else if(i==0 && row==1){
print_design(11,-1);
}
//for all other values
else{
print_design(7,-1);
}
}
}
//method to print coloumn header
public static void print_coloum_header(){
for(int i=0;i<=SIZE;i++){
if(i==0){
print_design(1,-1);
}
else{
print_design(2,-1);

System.out.println();

System.out.println();

}
System.out.println();
print_row_label(1);

}
public static void main(String[] args) {
int i,j;
//to get the size from user
//if you don't want it comment next 5 lines
int n;
Scanner sc = new Scanner(System.in);
System.out.print("Enter the SIZE: ");
n = sc.nextInt();
Table.SIZE = n;
//code to print the table
//print coloum headers

Summary This week's lab is to create a simple multiplication table using nested loops and if statements. Prompt the user for the size of the multiplication table (from 2x2 to 10x10). Use a validation loop to display a warning if the number is less than 2 or greater than 10 and prompt the user to enter the data again until they enter a valid number Put a...

1.Write a Java program that computes the average of the values of a row in a twodimensional array. You should create a method with the following header: public static double averageRow(double[][] array, int row) Write a test program that reads a matrix from the user and a row index to calculate the average on. Print the result. 2.A square matrix is said to be an upper triangular matrix if the value of the cell is 0 when row > column....
java Write an application that input a number from the user and checks if all digits are prime numbers using method prime. The number entered can be of any size. If all digits are prime your program should stop. Use do/while for reading the input and any loop format to test if the number is prime. When checking the prime numbers don’t use an if to check numbers from 1 – 9; you need to find an algorithm to check...

After the loop, print out the average of the r squared and r cubed. Use...
NOTE: Write the Program in python as mentioned below and use while loop and flags as necessary. And please write the code following the program description given below. Directions: Read the program description below carefully. All requirements must be met by your program to receive full credit. Thus, pay particular attention to input and output requirements, structural requirements, and so on.
