conditional constructs in Java

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

• Hello World

  Error

Re-write above statement using ternary operator-

• if(X<=Y) then X=Y else Y=X;

• if(X<=Y) ? X=Y : Y=X;

• (X<=Y) ? X=Y : Y=X;

int marks = 50;

if( marks > 70 )

System.out.println("Distinction");

else if( marks > 35 )

System.out.println("Pass");

else

System.out.println("Fail");

• Pass

• Distinction

• Fail

• Pass

  Fail

int marks = 80;

if( marks > 70 )

System.out.println("Distinction");

System.out.println("Congratulations");

else if( marks > 35 )

System.out.println("Pass");

• Distinction

  Congratulations

• Pass

• Distinction

• Error

"if" is a conditional construct?

• True

• False

What will be the output of following statement-

System.out.println('A'=='a');

• A==a

• 65==97

• true

• false

The if -else statement executes a block of code if a specified condition is

• true

• false

• both of these

• None of these

If there is Only one statement to be executed in if else block,giving braces are

• must

• optional
