Question

编写java应用程序，定义byte，ine，long，float，double，char和boolean等类型的数据，并用一个输出语句输

谢谢。

Answer 1

int a = 1;
boolean b = false;
char c = 'c';
long d = 2;
float e = 3.0f;
byte f = 4;
double g = 5.0;
System.out.print(a+" "+b+" "+c+" "+d+" "+e+" "+f+" "+g+" ");
输出的时候，将所有的对象转换为String类型输出了

Answer 2

// all of dataType you wanted and put into the object array
public Object []allDataTypes(){
byte bt=127;
int it=128;
long lg=2000L;
float ft=3423.1F;
double db=23123d;
char ch='c';
boolean bn=1==1;
Object ob=new Object[]{bt,it,lg,ft,db,ch,,bn};
return ob;
}

//the enter of programm;
public static void main(String []args){
Object []ob=allDataTypes(){;
for(int index=0,size=ob.length();index++)
System.out.println(ob[index])//print the result

}
