Question

我正在尝试创建一个程序，该程序将在年初输出值，在年内折旧的金额以及该寿命期内给定的每年的总折旧总额。例如，如果我在2005年购买了一件商品，并且其使用寿命为5年，它将计算该商品在这5年中的折旧。

我不太确定从哪里开始这个项目，这就是我到目前为止所掌握的。但是，这时我陷入了困境，现在我不确定下一步该怎么做。

import java.util.Scanner;

public class ConnerCozineDepreciation {
    public void main(String[] args){

    Scanner keyboard = new Scanner(System.in);
    int item, year, cost, life, depreciationType, depreciationDuring, totalDepreciation, begPrice;
    //GEt all the needed data from the user
    System.out.println("What is the item");
    item=keyboard.nextInt();
    System.out.println("What is the year of purchase?");
    year=keyboard.nextInt();
    System.out.println("How much did it cost? (No decimals)");
    cost=keyboard.nextInt();
    System.out.println("What is the item's estimated life span in years?");
    life=keyboard.nextInt();
    System.out.println("What is the method of depreciation?(1 for straight line or 2 for double decline)");
    depreciationType=keyboard.nextInt();

    //PRints the description and other info of the item
    System.out.println("Item:"+item);
    System.out.println("Year of Purchase: "+year);
    System.out.println("Cost of Purchase: "+cost);
    System.out.println("Estimated life: "+life);
    if(depreciationType ==1) {
        System.out.println("Straight line");
    }else{
        System.out.println("Double Decline");
    }

    System.out.println("Year\tValue at Beginning of Year\t\t"
                        +"Amount Depreciated During Year\t\tTotal Depreciated at End of Year");
    //Calculations of depreciations
    if(depreciationType==1) {
        while(year<=(year+life)){ //running only as many lines as wanted 

            year+=1;



            //System.out.format("%-8d" + "$%-39.2d"+ "$%39.2d" + "$%42.4d%n", year, cost, depreciationDuring, totalDepreciation);
        }



    }else {

    }

}


}

我认为您正在寻求降低生活价值

while (life > 0) {  
    year++; life--; // as it gets more age, it has less life 
}

否则写为

for ( ; life > 0; life--) {
    year++;
}

根据其他条件，您可能想尝试一下，尽管

life -= depreciationType;

While循环折旧（帮助）
