Hi can someone please explain why I have an error in my code... I'll post it below , thanks!

Your code looks perfect. Small, maintainable, and zero chance of bugs occurring.

This takes cryptic code questions to a new level.

I'm going to guess the error is on line 47

Look to me like a runtime error - much harder to debug......

Sorry i had to go before i had a chance to reply,

String station [] = {"Belmullet", "Mace Head","Shannon", "Valentina", "Sherkin Island" };
String month [] = {"July", "August","September", "October"};

double rainfall [][] = {{131.3, 96.3, 118.1, 76.3},
{128.2, 78.8, 166.9, 60.9},
{82.7, 93.4, 87.9, 49.7},
{120.5, 126, 148.9, 96.1},
{127,87,121.2,52.8}};

for (int i=0; i<month.length;i++){
System.out.printf("%20s", month);
}
for (int i=0; i<station.length;i++){
System.out.printf("\n%-10s", station);
}
for (int i=0; i<rainfall.length;i++){
System.out.println();
for (int j=0; j<rainfall.length;j++){
System.out.printf("%20.1f", rainfall[j]);
}
}
}
}



How do i get the doubles on the same line as the stations just accross.

You need to have a loop which prints each station, and inside this loop another loop which prints the rainfall figures for each corresponding station on the same line.
