問(wèn)題1：在Java中，除法分為取整和取余，不是直接得到計(jì)算結(jié)果的。
解決的辦法：
計(jì)算值的變量和結(jié)果值的變量類型應(yīng)該是浮點(diǎn)型，即double或者是float

// TestCompute.java 主函數(shù)
package demo1;

public class TestCompute {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        GoCompute comput = new GoCompute();
        comput.add(11,25);
        comput.div(3,8);
    }

}

// GoCompute.java 構(gòu)造函數(shù)
package demo1;

public class GoCompute {
    double valueOne;
    double valueTow;
    double result;
    
    public void add(int valueOne, int valueTow) {
        this.valueOne = valueOne;
        this.valueTow = valueTow;
        this.result = this.valueOne + this.valueTow;
        
        System.out.println("valueOne：" + this.valueOne);
        System.out.println("valueTow：" + this.valueTow);
        System.out.println("計(jì)算結(jié)果：" + this.result);
    }
    public void div(int valueOne, int valueTow) {
        this.valueOne = valueOne;
        this.valueTow = valueTow;
        this.result = this.valueOne / this.valueTow;
        System.out.print("計(jì)算結(jié)果：" + this.result);
    }
}
