String name ="David";
int age = 42;

Answer 1

you must use System.out.println();
like

class MyClass {
public static void main(String[ ] args) {
String name ="David";
int age = 42;
double score =15.9;
char group = 'Z';
System.out.println(name);
System.out.println(age);
}
}

Answer 2

they have many usages
the println function merely print the given parameter to the terminal

you can use this function on the other variables as well

Answer 3

you can make about everything with them
from basic mathematical operations to complex analysis of black holes or whatever

it all depends on the depth of which you research and learn :)

calculate the year you were born for example

class MyClass {
public static void main(String[ ] args) {
int YEAR = 2016;
int age = 26;
System.out.println("You were born in:" + (YEAR-age));
}
}
