Write an if statement that assigns 0 to \(x\) when \(y\) is equal to 20.
Rewrite the following if-else statements as statements that use the conditional operator. a) if (x > y) z = 1; else z = 20; b) if (temp > 45) population = base * 10; else population = base * 2; c) if (hours > 40) wages *= 1.5; else wages *= 1; d) if (result >= 0) System.out.println("The result is positive.)"; else System.out.println("The result is negative.");
Write an if-else statement that assigns 0 to the variable b and assigns 1 to the variable c if the variable a is less than 10. Otherwise, it should assign -99 to the variable \(b\) and assign 0 to the variable \(c\).
Assume that the double variable number holds the value \(459.6329 .\) What format pattern would you use to display the number as \(00459.633 ?\)
Rewrite the following if-else-if statement as a switch statement. if (selection == 'A') System.out.println("You selected A."); else if (selection == 'B') System.out.println("You selected B."); else if (selection == 'C') System.out.println("You selected C."); else if (selection == 'D') System.out.println("You selected D."); else System.out.println("Not good with letters, eh?");
