Java Conditional Constructs

public void main()

{

double temp = 56.0;

if (temp <=54.0 && temp>40)

System.out.println(“It is too hot”);

else if ( temp<40 || temp>30)

System.out.println(“It is hot but not too much”);

else

System.out.println(“It is pleasant”);

}

What will be the output?

• It is too hot

• It is pleasant

• It is hot but not too much

• runtime error

PREDICT THE OUTPUT:

int x = 20;

int y = 18;

if(x>y)

System.out.println("x is greater than y");

else

{

System.out.println("Error");

System.out.println("Incorrect code");

}

• Error

• Incorrect code

• x is greater than y

• Error

  Incorrect code

PREDICT THE OUTPUT:

int x = 60;

int y = 90;

if (y%x == 0 && y-x==30)

{

System.out.println("Hello World");

}

else

{

System.out.println("Error")

}

• Hello World

• Hello World

  Error

• Error

• Hello world

What will be the output of above statement-

• 5

• No output

• 6

• Error

5. If a, b and c are the sides of a triangle then which of the following statement is true for:

if(a==b && a==c && b==c)?

• Equilateral triangle

• Scalene triangle

• Isosceles triangle

• All of the above

In a switch case, when the switch value does not respond to any case then the execution transfers to:

• break

• default

• loop

• none

Condition is essentially formed using:

• Arithmetic operators

• Relational operators

• Logical operators

• None

Which of the following is a conditional statement?

• if

• if else

• if else if

• all of the above

Which of the following statement accomplishes ‘fall through’?

• if else

• switch

• for

• nested if

A Java program executes but doesn’t give the desired output. It is due to:

• logical error

• syntax error

• run time error

• none
