1.3 Exercises

1.True/False: All variables, parameters, and methods must have a declared type in Java, and the type can never change.
2.Suppose we have a function smaller(a, b) that takes in two int arguments a and b and returns the smaller of the two. What would the expression String x = smaller(10, 20) + 3; output?
3.Choose all statements that are true in Java: 
All code must be part of a class.
The end and beginning of code segments are delimited using curly brackets {}. 
All statements in Java end with a semi-colon ;.
Any code we want to run must be inside of a function public static void main(String[] args). 
Solutions
1.True. See "Static Typing" for more information.
2.This line of code would cause a compilation error because the declared type String is incompatible with the type returned by smaller and adding 3, which would be an int.
3.All the following statements are true.
