- Design a Java class named LinearEquation for a 2-by-2 system of linear equations:ax + by = e x=(ed-bf)/(ad-bc)cx + dy = f y=(af-ec)/(ad-bc) The class contains:• Private double data fields a, b, c, d, e, and f.• A constructor with the arguments for a, b, c, d, e, and f.• Six getter methods for a, b, c, d, e, and f.• Methods getX() and getY() that return the solution for the equation.• A method named isSolvable() that returns true if ad - bc is not 0. The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”. Write a Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.New Java code and only go between gery blocks of code (line 10 - line 12).ITERATORS IN JAVA Re-write this program using Java Iterators but without changing the meaning and consequently producing the same output. class TwoDArray { public static void main(String args[]) { int i, j, k = 0, twoD[][] = new int[4][5]; for(i = 0; i < 4; i++) for (j = 0; j < 5; j++) twoD[i][j] = k++; for(i = 0; i < 4; i++) { for(j = 0; j < 5; j++) System.out.print(twoD[i][j] + " "); System.out.println(); } } }
