Question

I have a variable of type Hashmap<String,Integer>.

In this, the Integer value might have to go some manipulation depending upon the value of a flag variable. I did it like this…

Hashmapvariable.put( somestring,     if (flag_variable) {      //manipulation code goes here      new Integer(manipulated value);     } else {      new Integer(non-manipulated value);     } ); 

But I get an error:

Syntax error on token(s), misplaced constructs.

at the Hashmapvariable.put call.

I also get another error

Syntax error on token ‘)’, delete this token.

at the final ‘);’ line. But I can’t delete the ‘)’ – its the closing parentheses for the put method call.

I don’t get this. What mistake am I doing?

Answer 1

You cannot place a statement in the method call.

However, one option could be to make an method that returns a Integer such as:

private Integer getIntegerDependingOnFlag(boolean flag) {     if (flag)         return new Integer(MANIPULATED_VALUE);     else         return new Integer(NON-MANIPULATED_VALUE); } 

Then, you can make a call like this:

hashmap.put(someString, getIntegerDependingOnFlag(flag));
