I've a FileOutputStream and a cicle like that:
PrintStream output = new PrintStream(new FileOutputStream("XXXX.json"));
output.print("{\"ObjectsList\": [");
for (int i = 0; i < something.length; i++) {
output.print("{"AAAA"},");
}
output.print("]}")
But I don't need the char "," before that output.print("]}");
How can I write at EOF-1 or EOF-2 for overwrite the last char ","
Stop the loop at something.length - 1 and make a last call to print with output.print("{ AAAA"}");
String var = "";
var = "{\"ObjectsList\": [";
for (int i = 0; i < something.length; i++) {
var = "{"AAAA"},";
}
//var.substring(0, var.length()-1) => remove the last char
output.print(var.substring(0, var.length()-1) + "]}");
Try something like this:
output.println("{\" ObjectsList \": [");
for(int i=0;i<something.length;i++){
String out="{\""+i+"}";
if(i!=something.length-1 ){
out+=", ";
}
output.println(out);
}
output.print("]}");
