      StringBuilder builder = new StringBuilder();

      int count = -1;
      while ((count = inputStreamReader.read(buffer, 0, buffer.length)) != -1) {
        builder.append(buffer, 0, count);
      }

      return builder.toString();
    }

  }

import com.sample.app.util.FileUtil;

public class SelectRadioButton {

  public static void main(String[] args) throws IOException, InterruptedException {
    try (Playwright playwright = Playwright.create()) {
      Browser browser = playwright.chromium()
          .launch(new BrowserType.LaunchOptions().setHeadless(false).setSlowMo(100));
      final String content = FileUtil.resourceAsString("actions" + File.separator + "selectRadioButton.html");

      Page page = browser.newPage();
      page.setContent(content);

      System.out.println("Selecting Java langauge");
      page.getByLabel("java").click();
      System.out.println("Is Java langauge checked : " + page.getByLabel("java").isChecked());
      System.out.println("Is Go langauge checked : " + page.getByLabel("go").isChecked());
      System.out.println("Is Python language checked : " + page.getByLabel("python").isChecked());
      TimeUnit.SECONDS.sleep(2);

      System.out.println("\nSelecting Go langauge");
      page.getByLabel("go").check();
      System.out.println("Is Java langauge checked : " + page.getByLabel("java").isChecked());
      System.out.println("Is Go langauge checked : " + page.getByLabel("go").isChecked());
      System.out.println("Is Python language checked : " + page.getByLabel("python").isChecked());
      TimeUnit.SECONDS.sleep(2);

    }
  }

}

Output

Selecting Java langauge
Is Java langauge checked : true
Is Go langauge checked : false
Is Python language checked : false

Selecting Go langauge
Is Java langauge checked : false
