java full trikey question

Problem 07:

What is the output of  the following question

  float income=12000,tax=0;

 if (income <= 10000)

tax = income * 0.1f;

else if (income <= 20000)

tax = 1000 +10000;

 System.out.println(tax);

Output:

11000

Problem 08:

What is the output of  the following question

float income=12000,tax=0;

if (income <= 10000)

tax = income * 0.1f;

else if (income > 10000 &&income <= 20000)

tax = 1000 +income*0.15f;

System.out.println(tax);

Output:

2800.0

Problem 09:

What is the output of  the following question you enter 2 3 4

Scanner input= new Scanner(System.in);

     double x = input.nextDouble();

double y = input.nextDouble();

double z = input.nextDouble();

System.out.println("(x < y && y < z) is " + (x < y && y < z));

System.out.println("(x < y || y < z) is " + (x < y || y < z));

System.out.println("!(x < y) is " + !(x < y));

System.out.println("(x + y < z) is " + (x + y < z));

System.out.println("(x + y > z) is " + (x + y > z));

Output:

 2

3

4

(x < y && y < z) is true

(x < y || y < z) is true

!(x < y) is false

(x + y < z) is false

(x + y > z) is true
