1, Write a java program named Suansu , define two integer variables A and B, initialize a to 10 and B to 5 using the construction method, and define a method to find the sum (method name AddAB), difference (method name SubAB), product (method name MultiAB) and quotient (method name DivAB). Use another Java program testsuansu Java test suansu Java defined methods and output the results on the screen. 2, Create a class named Rectangle to represent a rectangle whose width and height are changed. The width and height of the rectangle are determined by the construction method. Create the following methods for the rectangle class: Getarea returns the area of the rectangle. The range of length and height is required to be 0~50%3; Getperimeter returns the perimeter of the rectangle;

Write, Compile and Execute a Java program that prompts the user to enter a point (x, y) and checks whether the point is within the circle centered at (0, 0) with radius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, as shown in Figure below. (Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10. The formula for computing the distance is the square root of ((x₂-x₁)² + (x2 - y1)²). Test your program to cover all cases.) y-axis A (4,5) (0, 0) (9,9) Two sample runs are shown below. x-axis y-axis A (2,2) (0,0) Enter a point with two coordinates: 2 2 Enter Point (2.0, 2.0) is in the rectangle Enter a point with two coordinates: 6 4 Enter Point (6.0, 4.0) is not in the rectangle (6,4) x-axis
