Answer 1

You're looking for something like:

String.format("%20s     %05d   %10dd   %12d", name, icNumber, income, amount);

%20s means: Print a string, and if it's shorter than 20 characters, pad it out to the right by adding spaces. The formatter page explains it all. %05d means: Print a number, pad it out if it's less than 5 long, and pad it with zeroes instead of spaces. And so on.

In your Class, you first need to create Getters:

public void getName(){
return name;
}
public void geticNumber(){
return icNumber;
}
public void getincome(){
return income;
}
public void amount(){
return amount;
}

After that you can print out your desired text in your Main:

System.out.println("name     iCNO     taxableincome     taxableAmount);
System.out.printf("%s     %d     %d     %d",yourClass.getName(),yourClass.geticNumber(),yourClass.getincome(),yourClass.amount())

Alternatively you can edit your .toString in your Class like this:

String format = String.format("name     iCNO     taxableIncome     taxableAmount%n%s     %d     %d     %d",person,taxableIncome,status,taxAmount);
