 |
|
I have an array that is fed numbers (each on separate lines) by an infile
(File.txt). In a separate class, I needed to create a method to print each
number on the same line and be separated by a space. Is this code the correct
way to reference each separate line of data and print them all together?
double[] data = new double[5];
double ave;
//print all numbers on a line with spaces between them
public static printIt(data) {
for (int index = 0; index < data.length; index++)
outFile.print(data[index]+ " "); }

Almost...
The method signature needs a return type (.e.g.'void'),
and the argument 'data' also needs a type, (e.g. 'double[]').
| Quote: | public static printIt(data) {
for (int index = 0; index < data.length; index++)
|
'outFile' must be declared as a 'static' variable in the class, otherwise
the method can't reach it.
| Quote: | outFile.print(data[index]+ " "); }
|
Apart from those little things, it should work...
