JAR Javaコンパイル済みプロジェクトから.txtファイルに書き込むにはどうすればよいですか?
プロジェクトを実行してもエラーは発生しませんが、JARファイル内の.txtに書き込まれません。
以下を使用してJARファイルを作成します。
netbeans clean /build tool
コード:
public class FileIO {
private File file;
private Scanner filescScanner, lineScanner;
private PrintWriter fileWriter;
private String[][] data;
public FileIO () {
data = new String[100][2];
}
public String[][] getLineScores(){
return this.loadHighscores(this.getClass().getResourceAsStream("LineHighscores.txt"));
}
public String[][] getTimeScores(){
return this.loadHighscores(this.getClass().getResourceAsStream("TimeHighscores.txt"));
}
public void setLineScores( String name,String lines ){
boolean found= false;
data = this.getLineScores();
for(int i = 0; i<data.length && !found ; i++){
if(data[i][0] == null || "Niemand".equals(data[i][0])){
data[i][0]=name;
data[i][1]=lines;
found=true;
}
}
this.saveHighscores(this.getClass().getResource("LineHighscores.txt"),data);
}
