In class Song, write the calculation in method getEstEarnings of class Song to evaluate estimated earnings. Note that while in the real world, other methods would be used to estimate earnings, in this simplified model, the estimated earnings will be the length of the title, multiplied by the a value extracted by the ministry using the method getSongPartEst(hint.. the singer keeps a reference to the ministry. You can observe how the reference is used in method getClaimableEarnings). class Song { private String title, genre; Singer singer; private Studio studio; public Song(String title, String genre,Singer singer int, length) { this.studio = null; this.genre = genre; this.singer = singer; this.title = title; } public int getEstEarnings() { return 0;//Q2. Perform this calculation } public int getClaimableEarnings() { int est = getEstEarnings(); if (est > singer.getMinistry().getMinClaimable()) return est; else return 0; } public String getTitle(){ return title; } /* Q4A. you will implement setStudio somewhere around here */ public Studio getStudio(){ return studio; } private boolean isBestSeller() { return getEstEarnings()>singer.getMinistry().getBestSellLimit(); } public boolean hasStudio() { return (!(studio==null)); } public String toString() { String outval ="Released "; if (isBestSeller()) outval+="**"; int cost =0; if (!(studio==null)) cost = studio.getCost(); outval+=title+" as a "+genre + " single to earn $"+String.format("%,d", getEstEarnings())+"."; return outval; } }
