- Records / Record Classes/li>
- Pattern Matching for instanceof
- Sealed Classes
- Pattern Matching for switch
Local-Variable Type Inference – var
var url = new URL("http://www.openjdk.com/");
var con = urk.openConnection();
var is = new InputStreamReader(con.getInputStream());
var reader = new BufferedReader(is);
Switch Expressions
return switch(day) {
case MONDAY, FRIDAY, SUNDAY -> 6;
case TUESDAY -> 7;
case THURSDAY, SATURDAY -> 8
case WEDNESDAY -> 9;
};
Text Blocks
var html += """
<tr>
<td>Retweets: %s</td>
<td>Likes: %s</td>
</tr>
""".formatted(t.getRetweetCount(),
t.getLikeCount());
Records / Record Classes
record Point (int x, int y) {}
Pattern Matching for instanceof
if (obj instance of String s) {
// String s = (String) obj not necessary anymore
}
[/code]
<h4>Sealed Classes</h4>
[java]
public abstract sealed class Shape permits Circle, Rectangle, Square {...}
public final class Circle extends Shape {...}
public sealed class Rectangle extends Shape permits TransparentRectangle,
FilledRectangle {...}
public final class TransparentRectangle extends Rectangle {...}
public final class FilledRectangle extends Rectangle {...}
public non-sealed class Square extends Shape {...}
Pattern Matching for switch
static String formatterPatternSwitch(Object o) {
return switch(o) {
case Integer i -> String.format("int %d", i);
case Long l -> String.format("long %d", l);
case Double d -> String.format("double %f", d);
case String s -> String.format("String %s", s);
default -> o.toString();
};
}
Pattern Matching for switch – Matching null
static String formatterPatternSwitch(Object o) {
return switch(o) {
case null -> "null";
case Integer i -> String.format("int %d", i);
case Long l -> String.format("long %d", l);
case Double d -> String.format("double %f", d);
case String s -> String.format("String %s", s);
default -> o.toString();
};
}

Test & Measurement (T&M): SICL, SCPI and VISA
- SICL: Standard Instrument Control Library
- SCPI: Standard Commands for Programmable Instruments
- VISA: Virtual Instrument Software Architecture
- LXI: Lan eXtensions for Instrumentation
- Die moderne Alternative zum virtuellen COM Port (VCP) istdie Ansteuerung mit Hilfe der USB-TMC-Klasse. TMC stehtdabei für die „Test & Measurement Class” und bedeutet,dass bei installierten VISA-Treibern das angeschlosseneMessgerät ohne spezielle Windows-Treiber erkannt wirdund in den entsprechenden Umgebungen direkt verwendetwerden kann
- Bei der klassischen Variante des VCP kann der Anwendernach Installation der entsprechenden Windows-Treiber miteinem beliebigen Terminal-Programm über SCPI-Komman-dos mit dem HMC kommunizieren
