Java Data Type - 如何将Long转换为数字原始数据类型示例

       

public class Main {

  public static void main(String[] args) {
    Long lObj = new Long("10");
    byte b = lObj.byteValue();
    System.out.println(b);

    short s = lObj.shortValue();
    System.out.println(s);

    int i = lObj.intValue();
    System.out.println(i);

    float f = lObj.floatValue();
    System.out.println(f);

    double d = lObj.doubleValue();
    System.out.println(d);
  }
}
