public static void main(String[] args) {

// java keywords
// int int=1990;

if (score < 100 && score > 40) { // Expression (....)
System.out.println();// Expression
}

}
}

Statements:

Program;

public class Statements {

public static void main(String[] args) {

int myNumber = 90;

myNumber++;

myNumber--;

System.out.println("This is a test");

System.out.println("This is" + "another print " + " linse " + " example");

int var2 = 70;myNumber--;System.out.println("Same line demo....");

}

}
