Java – converts a class object to a human readable string

Is there any way to automatically convert custom class objects to human readable strings?

For example, consider the following courses:

class Person {
    String Name;
    int Salary;
    ...
}

Person p = new Person();
p.setName("Tony");
p.setSalary(1000);

I need something similar:

Person: Name="Tony",Salary=1000

Solution

Tostringbuilder can be used to import commons Lang

Check the method reflectiontostring (Java. Lang. object), which will automatically create the representation you want

This Code:

Person p = new Person();
p.setName("Tony");
p.setSalary(1000);

System.out.println(ToStringBuilder.reflectionToString(p));

The result is this string:

Person@64578ceb[Name=Tony,Salary=1000]
