This is Java. I need the PSEUDOCODE (or) FLOWCHART for the following source code.

SOURCE CODE:

CourseGradeDemo.java

public class CourseGradeDemo { public static void main(String args[]) { GradedActivity lab = new GradedActivity(); lab.setScore(85); PassFailExm pfExm=new PassFailExm(20,3,70); Essay essay=new Essay(); essay.setEssayvalues(25,18,17,20); FinalExm finalExm=new FinalExm(50,10); CourseGrades course=new CourseGrades(); course.setLab(lab); course.setPassFailExm(pfExm); course.setEssay(essay); course.setFinalExm(finalExm); System.out.println(course); }

}

CourseGrades.java

import java.util.Arrays;

public void setPassFailExm(PassFailExm pfe) { ga[1]=new GradedActivity(); ga[1].setScore(pfe.getScore()); }

public void setEssay(Essay e) { ga[2]=new GradedActivity(); ga[2].setScore(e.getScore()); }

public void setFinalExm(FinalExm fe) { ga[3]=new GradedActivity(); ga[3].setScore(fe.getScore()); }

/* * (non-Javadoc) * * @see java.lang.Object#toString() */ @Override public String toString() { String s = new String("Lab Score :" + ga[0].getScore() + " Grade:" + ga[0].getLetterGrade() + " Pass/Fail Exm Score :" + ga[1].getScore() + " Grade:" + ga[1].getLetterGrade() + " Essay Score :" + ga[2].getScore() + " Grade:" + ga[2].getLetterGrade() + " Final Exm Score:" + ga[3].getScore() + " Grade:" + ga[3].getLetterGrade()); return s; }
