基本数据类型课上练习

package hjsg;

public class fff {

    public static void main(String[] args) {

        System.out.println("hello");
        byte mybyte=121;
        System.out.println("mybyte=124");
        short myshort=2456;
        System.out.println(myshort);
        
    int myint=123654;
    long mylong=313131352123L;
    
    System.out.println(mybyte+myshort*myint*mylong)    ;
    float myfloat=3.25642f;
    double d1=125.321;
    char mychar=‘a‘    ;
    System.out.println(mychar);
    double result=mybyte+myshort+myint+mylong+myfloat+d1;
    System.out.println(result);    
    char mychar2=97;
    System.out.println(mychar2);
    System.out.println("今天学了数据类型\n我很高兴");
    System.out.println("今天学了数据类型\r我很高兴");
    boolean good=true;
    boolean bad=false;
    System.out.println(good);
    final int fist=1;
    System.out.println(fist);
        
        
    }
