Java Display Help

Hi i want to display a set of data and such as doubles but the zero`s after the decimal is messing everything up.How can i display this using system.out.println or printf without rounding of the doubles. . I am using System.out.printf. Heres the code


void SchoolArrays(){
String Schools[] = {"Sutherland: ","Waterkloof: ","GlenhighSc: ","Riverhighc: ","Soweto high "};
double Metal[] = {56.5,32.4,103.2,46.7,82.3};
double Glass[] = {12.2,67.9,35.6,72.2,89.9};
double Paper[] = {95,19.1,9.3,53.6,29.1};
double Other[] = {32.4,43.2,0.5,39.4,13.2};
//Question 9
for(int x = 0;x<Metal.length;x++){
OverAllWeights = OverAllWeights + Metal[x] + Glass[x] + Paper[x] + Other[x];
}
System.out.printf("%s %10s %5s %5s %5s %5s","SchoolName","Metal","Glass","Paper","Other","Totals");
for(int x = 0;x<Schools.length;x++){
Total[x] = Metal[x] + Glass[x] + Paper[x] + Other[x];
System.out.printf("%s %5.0f %5.0f %5.0f %5.0f %8.0f","\n"+Schools[x],Metal[x],Glass[x],Paper[x],Other[x],Total[x]);
}
for(int x = 0;x<Schools.length;x++){
metal = metal + Metal[x];
glass = glass + Glass[x];
paper = paper + Paper[x];
other = other+Other[x];
}
System.out.printf("%s %11.0f %5.0f %5.0f %5.0f %7.0f","\n"+"Totals:",metal,glass,paper,other,OverAllWeights);
}
}


And The output
SchoolName Metal Glass Paper Other Totals
Sutherland: 57 12 95 32 196
Waterkloof: 32 68 19 43 163
GlenhighSc: 103 36 9 1 149
Riverhighc: 47 72 54 39 212
Soweto high 82 90 29 13 214
Totals: 321 278 206 129 934

in printf, when using the "f" specifier for your parameters, the digit following the "." specifies how many digits you want shown after the decimal point ...

try:
System.out.printf("%s %5.1f %5.1f %5.1f %5.1f %8.1f", ...)
