What commands would return all the rows and columns in the ProductCategory table?
Delvig [45]

Answer:

Select commands would return all the rows and columns in the table.

Explanation:

In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.

Syntax of select command can be given as:

Select * from tablename;

Example:

select * from ProductCategory;

returns all the data from the table.

In select command, we will also return select data by using condition

SELECT column1 [, column2, ...]

FROM tablename

WHERE condition

In the conditional clause we use these operators that can be given as:

= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.

Write a class Bug that models a bug moving along a horizontal line. The bug moves either to the right or left. Initially, the bu
Harrizon [31]

Answer:

Explanation:

The following code is written in Java. It creates the Bug class with the position and direction variables. Then it creates a constructor, move method, turn method, and getPosition method. Finally, a bug object called bugsy is created in the main method, and we move it once to the right, then again to the right, and then we turn it and move it 5 times to the left, printing out the position when it is done moving. Output can be seen in the attached picture below.

class Brainly {

   public static void main(String[] args) {

       Bug bugsy = new Bug(10);

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

       bugsy.turn();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

   }

}

class Bug {

   char direction = 'r';

   int position = 0;

   public Bug(int initialPosition) {

       this.position = initialPosition;

   }

   public void turn() {

       if (this.direction == 'r') {

           this.direction = 'l';

       } else {

           this.direction = 'r';

       }

   }

   public void move() {

       if (this.direction == 'r') {

           this.position += 1;

       } else {

           this.position -= 1;

       }

   }

   public int getPosition() {

       return this.position;

   }

}
