If it’s not a B, then it knows that score < 80, and it continues that pattern for the rest of the program. It it is, then it displays the “Good job!” message and doesn’t check against any other grades since it already knows the grade is a B. If it’s not an A, then it knows that score 80. If it is, then it displays the “Congratulations!” message and doesn’t check any other grades since it already knows the grade is an A.

Think about it this way: first the code checks whether the grade is an A. But for the grade to be a B, it also has to be = 90, then the first if statement would have been entered, and the code wouldn’t even reach this line. Notice that the code only checks whether score >= 80. Try changing the score variable to see the different messages. If not, show the “Study more!” message.If so, show the “Not good!” message and stop checking any other conditions.If so, show the “Just okay.” message and stop checking any other conditions.If so, show the “Good job!” message and stop checking any other conditions.If so, show the “Congratulations!” message and stop checking any other conditions.

This code uses a series of if, else if and else statements to run this logic: To write an if statement, write the keyword if, then inside parentheses () insert a boolean value, and then in curly brackets If StatementsĪn if statement checks a boolean value and only executes a block of code if that value is true. But for now, keep in mind that boolean values contain true or false, and you can use operators like &, ||, and ! on them. There is a whole field of study devoted to boolean logic, so check that out if it sounds interesting. (If this bothers you because it doesn’t account for animals like bats, beavers, and dolphins… check out the homework!) Then it points the isMammal variable to that value. It then takes those values and feeds them into the & operator, which creates yet another boolean value. The and operator evaluates to true whenever the two boolean values on either side of it are also true.īoolean isMammal = ! canSwim & ! canFly įirst this code takes the opposite of the canSwim and canFly variables to create two new boolean values. You can combine two boolean values using the and operator, which looks like two ampersands: &. Similar to how you can add two float values using the + operator to get a third float value, or subtract them using the - operator, you can also operate on two boolean values to get a third boolean value. First you take the inequality score >= 90 and get a boolean value from it (in this case, true), and then you point the isGradeA variable to that value. If that line of code is confusing, try reading the right side first. So at the end of this code, isGradeA is holding the boolean value of true. In this case, the inequality is true because 95 is greater than 90. It then creates a boolean variable named isGradeA and sets it equal to the result of the inequality score >= 90. This code creates a float variable named score and sets it equal to 95. You create a variable by giving it a type, a name, and then a value:įloat score = 95 boolean isGradeA = score >= 90 For example, the int type holds whole numbers, the float type holds decimal numbers, and the String type holds text. Remember that a type tells the computer what kind of value a variable will hold. This tutorial also introduces if statements, which allow you to perform different actions depending on the value of a boolean. This tutorial introduces the boolean type, which can only hold two possible values: true or false. So far you’ve mostly worked with the float type. A type tells the computer what kind of data a value is, or what type of value a variable holds. You’ve seen that values have different types.
