GUI for testing constructors and methods in Eclipse (in Java) similar to BlueJ? -

i new java programming, , taking course through edx uses bluej ide. i'm trying duplicate in eclipse, since understand commonly-used ide professional programmers. have question functionality use in bluej haven't figured out yet in eclipse.

is there way create test instances of objects in eclipse can in bluej?

screenshot 1 shows 2 constructors available class. chose highlighted one.

screenshot 2 dialogue naming instance.

screenshot 3 dialogue menu various methods available object.

so there way in eclipse? have read bit junit, , intend learn use it, wondering if there similar function simple bluej testing in eclipse.

here code car class:

import comp102x.io; //external library available in many of later demo programs https://courses.edx.org/courses/course-v1:hkustx+comp102.1x+2t2015/f792f3a2057040aa959e606d687e9bc4/  /** * class of car objects can move forward, backward , turn */ public class car {         private int odometer = 0;           // odometer reading initialized 0         private string owner = "noname";    // name of owner      /**      *   default constructor car object      */     public car () {}        /**      *   constructor car object new owner’s name      *   @param   name                   name of owner      */     public car(string name) {   // constructor takes name argument         owner = name;     }      /**     *   movecar moves car forward or backward dist units     *   @param   dist     moving distance     */     public void movecar(int dist) {          odometer = odometer + math.abs(dist);         io.outputln(owner + "'s car has moved " + dist + " units.");      }      /**     *   turncar turns car given degree     *   @param   angle     turn angle in degrees     */     public void turncar(double angle) {          io.outputln(owner + "'s car has turned " + angle + " degrees.");      }      /**     *   getodometer gets odometer reading of car     *   @return     value of odometer     */     public int getodometer() {         return odometer;     }  } 

from experience in working bluej, can tell it's simplified beginners. there's lot of conveniences allowed end user stuff quick instantiation , quick testing.

however, you're not afforded such conveniences (graphically) in ide eclipse, netbeans, or intellij. these ides make easier develop enterprise level code, , such, graphical interface serve in way more help.

depending on context of "test", have several options.

• if want instantiate instance , play around it, create new class main method. there, instantiate instance of car hand:

  public static void main(string[] args) {     car car = new car();     car altcar = new car("the ride");     // code calls methods on each instance follow } 

• if want unit tests, junit choice. you'll have put junit somewhere on classpath (documentation eclipse exists).

  public class cartest {      @test     public void testcar() {         car car = new car();         // put state car         // assert expectations     } }
