My older approach This is the older, pre-Java 9 approach I used to use to create a static List in Java (ArrayList, LinkedList): If a method doesn’t use any instance members (non-static methods and non-static variables) of the class, you can consider make it as static. Array クラスは、Java 配列を動的に作成してアクセスするための static メソッドを提供します。 Array は、取得動作または設定動作中に起こる拡大変換は許可しますが、縮小変換が起こると IllegalArgumentException がスローされます。 int [] array = {1,5,10,8,9}; 変数arrayの配列の最小値は1、最大値は10となりますが、Javaの標準ライブラリでは配列の最大値と最小値を求める便利な標準ライブラリ(もともと用意されているクラスやメソッド)はありません。 I show my older approach below, but if you’re using Java 7 or Java 8, this seems like a good approach. Java byte Array byte Array in Java byte Array Java byte Array is used to store byte data type values only . 7. static boolean deepEquals(Object[] m1, Object[] m2): deepEquals method would return true in case the two mentioned arrays are deeply equal to the other array or not.
