I am writing a program which asks the user to enter name, age and country and should save the data in a file. The user should be able to delete, edit and view the data.
the output should be like this.
When I save the data it is stored in one text file. For example the user inputted the following. Name: John Wall, Age: 23, Country: Canada then it will save in a text file as “John 23 Country”. How can I able to load those data in their specific text box?
You have a couple of options
Write the contents to a database. A tutorial on writing to SQL lite should get your started [1]
If the information is meant for light weight storage (say this is just one entry) use shared preferences / file based persistence [2]
