In-Depth Information
SR4 . Write a conditional that stores x in z and y in x if z is greater than 0 .
SR5 . Write a conditional statement to set z to the minimum of x+y and x-y .
SR6 . In the following conditional statement, the else-part is written in English:
// Set d to the minimum of a , b , and c
if (a <= b && a <= c) {
d= a;
} else { // the minimum is b or c
Set d to the minimum of b and c
}
Replace the else-part by a Java statement to accomplish that task. You will end
up with a nested conditional statement : a conditional statement that appears
within another conditional statement.
SR7 . In the following conditional statement, the then-part is written in English:
// Set d to the maximum of a , b , and c
if (a<b||a<c) {
Set d to the maximum of b and c
} else { // the maximum is a
d= a;
}
Replace the then-part by a Java statement to accomplish that task. You will end
up with a nested conditional statement : a conditional statement that appears
within another conditional statement.
SR8 . Variables b , c , and d contain integers. Write a program segment that sets
boolean variable t to the value of “ b , c , and d are the lengths of the sides of a tri-
angle”. Three integers are the lengths of the sides of some triangle if and only if
the sum of any two sides is at least the third side.
For the answer to SR1, we provide class Chapter2Exercises and method sr1 .
For the rest, we provide only the conditional code.
SR1 . public class Chapter2Exercises {
public static void sr1( int x) {
if (x < 0) {
x= x + 1;
}
}
}
SR2 . A block is a sequence of statements delimited by (enclosed in) braces {
and } . It aggregates the sequence of statements into a single statement.
