======================
import java.io.Console;
public class ConsoleOutput {
public static void main(String arg[]) {
Console con;
con = System.console();
if(con == null) {
System.out.println("No console available.");
return;
}
int value = 31520;
con.printf("The number %d as hexidecimal is %4X/n",value,value);
}
}
注意Console这个类的read和write方法是synchronized，而且console可能不存在（当然，你要是使用cmd或者shell则一定存在），最好使用flush刷新display
