The if statement is used to implement a decision. The simplest form of an if statement has two parts: a condition and a body. If the condition is true, the body of the statement is executed. The body of the if statement consists of a statement block.

Consider the following program, which uses an if statement to output the smaller (minimum) of two numbers:

import java.io.*; import java.util.*; public class CPS150_Lab12 { public static void main(String[] args) { Scanner scan = new Scanner(System.in); PrintStream disp = System.out; // input variables int x; int y; // output variable int min; disp.println("Enter a value for x:"); x = scan.nextInt(); disp.println("Enter a value for y:"); y = scan.nextInt(); min = x; // assume x is smaller if (y < min) { min = y; } disp.println("The smallest value is " + min); } // end main method } // end class SmallestInt

Lab 12.1

First, copy-and-paste the highlighted code above to the main method of your NetBeans project. Then, modify the code so that it prompts the user to enter a third value for a variable z. Rewrite the logic so that the program prints out the smallest value contained in x, y, and z.

Lab 12.2

Modify the code from Lab 8.1 so that it prompts the user for four integers (w, x, y, and z) and prints the smallest value contained in those variables.

this is the code for lab 8.1

pen.setColor(Color.blue); pen.drawOval(100, 220, 300, 60); pen.setColor(Color.BLACK); pen.drawOval(185, 230,130,40); pen.setColor(Color.GREEN); pen.drawArc(185, 200, 130, 100, 0, 180); pen.setColor(Color.BLACK); pen.drawArc(130, 250, 250, 60, 160, 220); pen.setColor(Color.ORANGE); pen.drawArc(170, 280, 200, 60, 160, 220); pen.setColor(Color.red); pen.drawArc(215, 330, 100, 30, 160, 220);
