 ```// Define our new java class // Since we call it Class1 we must name our java file Class1.java public class Class1 { // The main function (called when you execute your program) public static void main(String[] args) { // declare a new variable myNumber as integer // it can now hold numbers (..,-2,-1,0,1,2,3,...n). // the default value = 0. int myNumber; // declare a new variable myDecimalNumber as double // it can now hold decimalnumbers ( -2.7 or 1.5) double myDecimalNumber; // declare a new variable myChar as char. It can hold a character. char myChar; // declare a new variable myBool as boolean // it can hold true or false (1 or 0). The default value = false. boolean myBool; // define the variable myNumber and set value equal to 5 myNumber = 5; // define the variable myDecimalNumber and set value equal to 8.8; myDecimalNumber = 8.8; // define the variable myChar as the character a. myChar = 'a'; // define the variable myBool as true. myBool = true; // Display myNumber System.out.println("my number: " + myNumber); // Display myDecimalNumber System.out.println("my decimal number: " + myDecimalNumber); // Display myChar System.out.println("my character: " + myChar); // Display myBool System.out.println("my boolean: " + myBool); } } // Learn to declare and define different variables and to display them. ```
