How to know the Employees.class is null or not using Java Relection?
Example Class: Employees.class
Problem:
Employees.Class
public class Employees{
private Long id;<br>
private String kodStuff;<br>
private String Name;<br>
//Getter and Setter<br>
}
Example Process Method:
public void check(){
Employees employees = new Empoyees;
employees.setName("Mikel");
employees.setKodStuff("KL370");
//employees not save yet and process redirect check value of Name wuth return boolean
Boolean empty = checkName(employees);
}
public boolean checkName(Employees employees){
boolean notNull = false;
if(employees !=null && StringUtils.isNotBlank(employees.getName())){ // this is line 11
notNull = true;
}
return notNull;
}
Throws exception at line no '11':
java.lang.NullPointerException
How can i check null exception during process on line no.11?
尝试通过执行以下操作检查employees.getName()
是否为空:
employees.getName() != null
