- 1). Click "Start" in the Windows Desktop and then click "Java JDK."
- 2). Click "File," select "Open" and then double-click on the Java program in which you want to import characters from the system console.
- 3). Add the following code after the "public void main()" line in your program:
import java.io.Console;
import java.nio.charset.Charset;
import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import static java.lang.System.out;
// store Console character set in the private field
public class ConsoleCharset {
public static void main(String... args) {
Constructor[] ctors =
Console.class.getDeclaredConstructors();
Constructor ctor = null;
for (int i = 0; i < ctors.length; i++) {
ctor = ctors[i];
if (ctor.getGenericParameterTypes().length == 0)
break;
}
// obtain the internal character set used by java.io.Console
try {
ctor.setAccessible(true);
Console c = (Console)ctor.newInstance();
Field f = c.getClass().getDeclaredField("cs");
f.setAccessible(true);
out.format("Console charset : %s%n", f.get
(c));
out.format("Charset.defaultCharset(): %s%n",
Charset.defaultCharset());
// intercept the system input exceptions
} catch (InstantiationException x) {
x.printStackTrace();
} catch (InvocationTargetException x) {
x.printStackTrace();
} catch (IllegalAccessException x) {
x.printStackTrace();
} catch (NoSuchFieldException x) {
x.printStackTrace();
}
}
} - 4). Click "File" and then click "Save" to add console access to your Java program.
