In this part you will learn about making a method We will be using this block of Java code for this part.
public class JavaIntro4 {
/*add 4 to the paramter sent to the method and return the result*/
public static double addFour(double num){ // the varible type before the method name is what type will be returned
return num + 4; //return is the keyword that tells java to end the method and send the value
}
/*if the boolean named bol is true than print out the double named num*/
public static void ifTruePrint(boolean bol, double num){ //void means the method won't return any value
if (bol){
System.out.println(num);
}
} //this method doesn't return a value
public static void main(String args[]) { //This line lets Java know what to run when you click execute below
boolean b1 = true;
boolean b2 = false;
double x = 10;
double y = 20;
System.out.println(addFour(x));
ifTruePrint(b1, x); //if b1 is true print x
ifTruePrint(!b1, y); //if b1 is not true print y
}
}
