使用java编写财务信息类，输入公司名称、定金收入、押金收入、租金收入、其它收入、员工成本、房租、水电、税收及其它费用，输出收入计算、成本计算、净收入计算。

可以使用以下代码实现：

public class FinancialInfo {
    private String companyName;
    private double downPaymentIncome;
    private double depositIncome;
    private double rentIncome;
    private double otherIncome;
    private double employeeCosts;
    private double rentCost;
    private double utilitiesCost;
    private double taxCost;
    private double otherCosts;

    public FinancialInfo(String companyName, double downPaymentIncome, double depositIncome, double rentIncome, double otherIncome, double employeeCosts, double rentCost, double utilitiesCost, double taxCost, double otherCosts) {
        this.companyName = companyName;
        this.downPaymentIncome = downPaymentIncome;
        this.depositIncome = depositIncome;
        this.rentIncome = rentIncome;
        this.otherIncome = otherIncome;
        this.employeeCosts = employeeCosts;
        this.rentCost = rentCost;
        this.utilitiesCost = utilitiesCost;
        this.taxCost = taxCost;
        this.otherCosts = otherCosts;
    }

    public void printIncomeCalculation() {
        System.out.println("Income Calculation for " + companyName);
        System.out.println("Down Payment Income: " + downPaymentIncome);
        System.out.println("Deposit Income: " + depositIncome);
        System.out.println("Rent Income: " + rentIncome);
        System.out.println("Other Income: " + otherIncome);
        double totalIncome = downPaymentIncome + depositIncome + rentIncome + otherIncome;
        System.out.println("Total Income: " + totalIncome);
    }

    public void printCostCalculation() {
        System.out.println("Cost Calculation for " + companyName);
        System.out.println("Employee Costs: " + employeeCosts);
        System.out.println("Rent Costs: " + rentCost);
        System.out.println("Utilities Costs: " + utilitiesCost);
        System.out.println("Tax Costs: " + taxCost);
        System.out.println("Other Costs: " + otherCosts);
        double totalCosts = employeeCosts + rentCost + utilitiesCost + taxCost + otherCosts;
        System.out.println("Total Costs: " + totalCosts);
    }

    public void printNetIncomeCalculation() {
        System.out.println("Net Income Calculation for " + companyName);
        double totalIncome = downPaymentIncome + depositIncome + rentIncome + otherIncome;
        double totalCosts = employeeCosts + rentCost + utilitiesCost + taxCost + otherCosts;
        double netIncome = totalIncome - totalCosts;
        System.out.println("Net Income: " + netIncome);
    }
}

然后，可以在主函数中创建一个实例并调用相应的方法：

public static void main(String[] args) {
    FinancialInfo financialInfo = new FinancialInfo("ABC Company", 5000.0, 2000.0, 10000.0, 500.0, 8000.0, 3000.0, 1000.0, 2000.0, 500.0);
    financialInfo.printIncomeCalculation();
    financialInfo.printCostCalculation();
    financialInfo.printNetIncomeCalculation();
}

输出结果如下：

Rent Income: 10000.0
Other Income: 500.0
Total Income: 17500.0
