コードを書いていて、parseIntvalueOfの違いがわからなかったので備忘録として残しておく。

#違い
 コードを実行したときに結果が同じになる。調べてみると戻り値が違うと出てきた。具体的には、parseIntがint型やchar型などのプリミティブ型でvalueOfはIntegerクラスを返す。

public class Main {
    public static void main(String[] args) throws Exception {
        int hoge = Integer.valueOf("12345");
        System.out.println(hoge);
        
        int fuga = Integer.parseInt("12345");
        System.out.println(fuga);
    }
}
実行結果
12345
12345
