Posted at

概要

Javaで「文字列や他の値を追加する」の動作を確認してみました。以下のページを参考にしました。

実装

以下のファイルを作成しました。

JSample1_2.java
class JSample1_2{
  public static void main(String[] args){
    StringBuilder sb = new StringBuilder();
    sb.append("Hey");
    sb.append(75.2);
    sb.append(18L);
    sb.append(true);

    System.out.println(sb.toString());
  }
}

以下のコマンドを実行しました。

$ javac JSample1_2.java 
$ java JSample1_2 
Hey75.218true
