Class 10 Revision of Class IX Syllabus Important Questions and Answers

Q1. What is the type and value of the following expression? (Notice the integer division) – 4 + 1/2 + 2*–3 + 5.0

Options

(a) int -5
(b) double -4.5
(c) int -4
(d) double –5.0

Ans. (d) double –5.0
Explanation:
The execution goes on like this:
– 4 + 1/2 + 2*-3 + 5.0;
– 4 + 0 + -6 + 5.0; // integer division: 1/2 truncates .5
– 10 + 5.0; // higher type is double 5.0, so -10 is casted to double
– 5.0; // finally, double -5.0.

Q2. How many times ‘Hello’ is printed?
Public static void main(String args[])
{
for(i = 0;i<5;i++)
{
System.out.println(“hello”);
break;
}
}

Options

(a) 5
(b) 4
(c) 1
(d) 0

Ans. (c) 1

Explanation:
It is printed one time only because break; will terminate the current loop.

Q3. Rewrite the following loop using for loop :

while (true)
System.out.println(“*”)

Explanation:
for(int i = 0; ;i++)
{
System.out.print(“*”);
}

Q4. Evaluate the expression :

z = ++x * (y– –)–y
where, x = 20, y = 10, z;

Explanation:
z = ++x * (y– –)– y
= 21 * (10) – 9
= 210 – 9 = 201

Q5. Rewrite the following condition without using logical operators :

if (a > b | | a > c)
System.out.println(a);

Explanation:
if (a > b)
System.out.println(a);
if (a > c)
System.out.println(a);
