Some simple java exercises for getting accustomed to the Netbeans interface and simple java code.

Description: Some simple java exercises for getting accustomed to the Netbeans interface and simple java code.

Create a new Netbeans Project, name it GettingStarted1

Netbeans > file > new project > choose project: java application <next> Project Name: GettingStarted <finish>

Your screen will now look something like:

public class GettingStarted1 {

    /**

    public static void main (String[] args) {
        //Your java code goes here
    }
}

This code will be delted and replaced with the code on the following page.

Delete all the above code, replace it with the follow code:

Type in code:

package asu.gettingstarted1;
import java.util.Scanner;

public class GettingStarted1 {

    public static void main(String[] args) {
        System.out.println("Hello World");

        System.out.println("1 + 2 + 3");
        System.out.println(1 + 2 + 3);
        System.out.println("1" + 2 + 3);
        System.out.println(1 + "2" + 3);
        System.out.println(1 + 2 + "3");
        System.out.println(1 + 2 + 3);

        System.out.println("a"+ "b" + "c");

        int a = 89;
        System.out.println(a + "b" + "c");

        Scanner input = new Scanner(System.in);
        System.out.println("Please enter the length");
        int length = input.nextInt();
        System.out.println("length = " + length);
        System.out.println("max integer = " + Integer.MAX_VALUE);
        System.out.println("max double = " + Double.MAX_VALUE);

        String x = "hello";
        x = x + " there";
        System.out.println("x = " + x);

        char z = 10036;
        for(int i = 40; i < 128; i++){
            System.out.println("Z = " + (char) i);
        }

    }

}

After clicking the green "Run" arrow on the menu bar you should get an output that looks like the follow (the computer will prompt you to enter a length → try 10)

Sample Output:

Hello World
1 + 2 + 3
6
123
123
33
6
abc
89bc
Please enter the length
10
length = 10
max integer = 2147483647
max double = 1.7976931348623157E308
