I'm writing a method to extract a certain substring, but I'm having problems calling that method. Code is as follows:
public void start() {
String inputString = "XOXOXOO X XXO X OXO ";
int row = 0;
int length = inputString.length();
System.out.println("Enter column for X:");
int column = Integer.parseInt(Keyboard.readInput());
}
enterToken("X", inputString,column);
private String enterToken(String tokenSymbol, String inputString, int column){
String columnEdit = inputString.substring(column*6-6,column*6);
String columnEdit1 = columnEdit.trim( );
String columnEdit2 = columnEdit1+tokenSymbol+" ";
String columnEdit3 = columnEdit2.substring(0,6);
System.out.println(columnEdit3);
return columnEdit3;
}
I'm getting error "Invalid method declaration; return type required". I feel sure I declared it properly..
enterToken("X", inputString,column);
You need to add return type for this line (or) this line should go inside a method.
System.out.println("Enter column for X:");
int column = Integer.parseInt(Keyboard.readInput());
enterToken("X", inputString,column);
}
}
enterToken("X", inputString,column);
Should be
enterToken("X", inputString,column);
}
Just to clarify what is happening here. The compiler thinks that you are trying to declare a method called "enterToken" but before it even parses the rest of the line it notices that you don't have a return type (or void) to begin with.
