[Java]配列

Posted at 2020-06-23

#配列の定義
データ型[]　配列名 = {};


String[] names = {"tanaka" , "sato" , "suzuki"};
System.out.println(names[0]);

#配列のfor文
配列の中身を全部出力する。

通常のfor文


String[] names = {"tanaka" , "sato" , "suzuki"};

for(int i = 0; i < names.length; i++) {
  System.out.println(names[i]);
}

拡張for文
for(データ型　変数:配列名){}


String[] names = {"tanaka" , "sato" , "suzuki"};

for(String name:names) {
  System.out.println(name);
}
