Java8で16進数の論理和を計算するのだ。

Last updated at Posted at 2022-12-08

いきさつ

  • 仕事で論理和のコードを書くことになったのだけれど、完全に忘れていたので調査した次第なのだ。

論理和とは

書いてみた

main.java
public static void calcOr(){
    Integer num1 = Integer.decode("0x007F");
    Integer num2 = Integer.decode("0x0030");
    
    Integer or = num1 | num2;
    System.out.println("OR(Decimal) : " + or);    // OR(Decimal) : 127
    System.out.println("OR(Hex) : " + Integer.toHexString(or));   // OR(Hex) : 7f
}
