If you have lots of these variables, have you considered putting them in a collection instead of having them as separate variables? There are various options at that point.
If you find yourself doing this a lot, you might want to write helper methods, possibly using varargs syntax. For example:
public static boolean areAllEqual(int... values)
{
if (values.length == 0)
{
return true; // Alternative below
}
int checkValue = values[0];
for (int i = 1; i < values.length; i++)
{
if (values[i] != checkValue)
{
return false;
}
}
return true;
}
An alternative as presented by glowcoder is to force there to be at least one value:
public static boolean areAllEqual(int checkValue, int... otherValues)
{
for (int value : otherValues)
{
if (value != checkValue)
{
return false;
}
}
return true;
}
In either case, use with:
if (HelperClass.areAllEqual(x1, x2, x3, x4, x5))
{
...
}
