public class Test{
public static void main (String args[]){
byte x=3;
char y=2;
int a=10;
boolean b=true;
float f=123.12f;
double d=120.12;
long i=122.12;
System.out.println(x);
System.out.println(y);
System.out.println(a);
System.out.println(b);
System.out.println(f);
System.out.println(d);
System.out.println(i);
}
}
第二題：
public class Test2{
public static void main (String args[]){
System.out.println("java很有趣。");
System.out.println("努力學好java編程。");
//起點坐標不知如何中設置//
}
}
第三題：
public class Test3{
public static void main (String args[]){
int i=12345;
System.out.println(i>>3); //右移3位相當於整除8
System.out.println(i<<3); //左移3位相當於乘以8
System.out.println(i*8);
System.out.println(i/8);
}
