The Switch Statement

[Everyman]

I have been stuck on this problem for 30 minutes:

" Write the definition of a method printAttitude , which has an int parameter and returns nothing. The method prints a message to standard output depending on the value of its parameter.

• If the parameter equals 1 , the method prints disagree
• If the parameter equals 2 , the method prints no opinion
• If the parameter equals 3 , the method prints agree
• In the case of other values, the method does nothing.

Each message is printed on a line by itself."


This is the code that I have assembled:

switch (numValues)
{
 case 1
   System.out.println("disagree");
   break;

case 2
  System.out.println("no opinion");
  break;

case 3
  System.out.println("agree");
  break;

default:
}

Every time I submit it to the compiler on MyProgrammingLab, it tells me that I have to "write the definition of the printAttitude method" or something like that. I have no idea how to do this and I looked at the API site and it looked kinda confusing... Could someone please lend a hand to this poor noob?

Where is your printAttitude method? All we can see is a single switch statement ...

Each message is printed on a line by itself.

System.out.println("-text-");
prints the stuffs in a new line, and also skips to next line for successor statements..
for example,

System.out.println("1st line");
System.out.print("2nd line");
System.out.print("3rd line");

output is

1st line
2nd line3rd line

note that
System.out.print();
requires a boolean or a string as an argument

That's what I don't understand. I have tried the public static int printAttitude and similar things but they didn't work. Was that the right track? Is there something that I am missing? I don't know...

int printAttitude

Jos knows the answer for this. wait for the answer

Well, thats my bell.

[noobplus]

public static int printAttitude

public static int printAttitude() returns an int.. but the code should not return any int's .. so
public static void printAttitude() should be the method

Do you know how to define a method? Look at your main( ... ) method for a static method that doesn't return anything. Your method should take a single int parameter.

This is kinda old, but I never successfully figured this out. Would the code look something like this:

public static void printAttitude(int);

{
case 1:
   System.out.println("disagree");
   break;

case 2:
  System.out.println("no opinion");
  break;

case 3:
  System.out.println("agree");
  break;
}

I feel like that "method does nothing" part is throwing me off...

That's not the correct syntax for defining a method, taking a parameter, or for setting up a switch statement. They are all covered in the basic tutorials.

Like this, right?

public          static       void        printAttitude      (    int      x    )
{
if          (           x       ==        1          )
{
System.out.println          (           "disagree"           )           ;
}
if            (         x         ==        2             )
{
System.out.println        (       "no opinion"           )         ;
}
if           (           x          ==         3         )
{
System.out.println            (           "agree"            )           ;
}
}

Well (barring the appearance of a huuuge amount of spaces there) the method signature is OK now, but you no longer have a switch statement in there.
