Your Turn: Declare and Initialize Variables Based on Descriptions
For the data descriptions
- Determine whether they are primitive data or object data.
- If they are primitive data, which of the 4 data types would be best to use to represent the data? The 4 primitive data types we will use are:
int, double, char, boolean.
- If it is primitive data, what would the initial value might be?
- If it is primitive data, write your statements in the Java playground.
Your Turn: Making Modifications to Variable Declarations
- For each of the following variable declarations, make modification so that the code works as intended.
Practice 1
- Declare and initialize a variable to store whether a person is considered an adult or not.
Practice 2
- Declare and initialize a variable to store the average weight of an apple.
Practice 3
- Declare and initialize a variable to store a letter grade.
Practice 4
- Declare and initialize a variable to the capacity of a bus.
