Can you help me with java?

Question

I'm trying to do an if-then-else statement that does something according to whether a y or n was inputted. What am I doing wrong?

if(keyboard.nextChar()='y' || keyboard.nextChar()='Y' )

{

System.out.println("What is the amount charged? ");

amountCharged = keyboard.nextFloat();

}

Answer 1

You are comparing a string ('y' and 'Y') using the equals ('=') operator. In Java this is fine for numbers, but in the case of strings, use the ".equals" method.

if(keyboard.nextChar().equals('y') || keyboard.equals('Y' ))

{

System.out.println("What is the amount charged? ");

amountCharged = keyboard.nextFloat();

}

and also when comparing, the correct operator is ('==') and not

('=') which is used for assigning values.

Answer 2

try this:

if( keyboard.nextChar() == 'y' || keyboard.nextChar() == 'Y'){

     //do something here

}

else if( keyboard.nextChar() == 'n' || keyboard.nextChar() == 'N'){

   //do something else here...

}

else{

   //neither y or n was pressed, handle that here...

The problem is the equal sign in your statement...

the sign = is an assignment statement like x = 5;

the sign == is used to compare like if (x == 5);

Good?
