Java : URI - API使用例

URI (Java SE 21 & JDK 21) の使用例まとめです。
だいたいのメソッドを網羅済みです。
API仕様書のおともにどうぞ。

概要

URI (Uniform Resource Identifier)参照を表します。

クラス構成

関連するクラスとしてURLクラスがあります。
「Java API 使用例 : URL」も参考にしていただけたら幸いです。

final var uri = new URI("https://example.com/java/index.html");
System.out.println(uri); // "https://example.com/java/index.html"
System.out.println(uri.getScheme()); // "https"
System.out.println(uri.getHost()); // "example.com"
System.out.println(uri.getPath()); // "/java/index.html"

コンストラクタ

URI (String str)

指定された文字列を解析してURIを構築します。

似た API に create(String str) メソッドがあります。
うまく使いわけましょう。

URI(String str) : str の解析に失敗するとチェック例外(URISyntaxException) がスローされます。
つまり、解析に 失敗するかも しれない文字列であるときに使います。(ユーザー入力など)
URI.create(String str) : str の解析に失敗すると非チェック例外(IllegalArgumentException) がスローされます。
つまり、解析に 失敗しない 文字列であることが事前にわかっているときに使います。(固定値など)

final var ret = new URI("");
System.out.println(ret); // ""

// 階層URI(絶対)
final var ret1 = new URI("http://example.com/languages/java/");
System.out.println(ret1); // "http://example.com/languages/java/"

final var ret1 = new URI("sample/a/index.html#28");
System.out.println(ret1); // "sample/a/index.html#28"

static URI create (String str)

指定された文字列を解析してURIを作成します。

このメソッドは、コンストラクタの URI(String str) とほぼ同等です。

URI.create(String str) は解析に失敗すると非チェック例外の IllegalArgumentException をスローします。
URI(String str) は代わりにチェック例外の URISyntaxException をスローします。

System.out.println(uri2.toASCIIString()); // "news:comp.lang.java"

final var uri3 = URI.create("http://example.com/♪");
System.out.println(uri3.toString()); // "http://example.com/♪"
System.out.println(uri3.toASCIIString());  // "http://example.com/%E2%99%AA"

final var uri4 = new URI("http", "example.com", "/a b c", null);
System.out.println(uri4.toString()); // "http://example.com/a%20b%20c"
System.out.println(uri4.toASCIIString()); // "http://example.com/a%20b%20c"

String toString ()

このURIのコンテンツを文字列として返します。

final var uri1 = URI.create("http://example.com/languages/java/");
System.out.println(uri1.toString()); // "http://example.com/languages/java/"
System.out.println(uri1.toASCIIString()); // "http://example.com/languages/java/"

final var uri2 = URI.create("news:comp.lang.java");
System.out.println(uri2.toString()); // "news:comp.lang.java"
System.out.println(uri2.toASCIIString()); // "news:comp.lang.java"

final var uri3 = URI.create("http://example.com/♪");
System.out.println(uri3.toString()); // "http://example.com/♪"
System.out.println(uri3.toASCIIString());  // "http://example.com/%E2%99%AA"

final var uri4 = new URI("http", "example.com", "/a b c", null);
System.out.println(uri4.toString()); // "http://example.com/a%20b%20c"
System.out.println(uri4.toASCIIString()); // "http://example.com/a%20b%20c"

URL toURL ()

このURIからURLを構築します。

final var uri = URI.create("http://example.com/languages/java/");
System.out.println(uri.toURL()); // "http://example.com/languages/java/"

final var uri = URI.create("../../demo/b/index.html");
try {
    final var ret = uri.toURL();
} catch (IllegalArgumentException e) {
    System.out.println("IllegalArgumentException! : " + e.getMessage());
}

// 結果
// ↓
//IllegalArgumentException! : URI is not absolute

final var uri = URI.create("news:comp.lang.java");
try {
    final var ret = uri.toURL();
} catch (MalformedURLException e) {
    System.out.println("MalformedURLException! : " + e.getMessage());
}

// 結果
// ↓
//MalformedURLException! : unknown protocol: news
