我目前正在处理一个包含多个学生对象的模块类,并且遇到了以下问题 -
一元运算符'+'的错误操作数类型字符串
我将不胜感激,我的代码如下。
public class Module {
private String moduleTitle;
int percentageCoursework;
int percentageExam;
private Student studentsList[] = new Student[3];
public Module (String moduleTitle, int percentageCoursework, int percentageExam,String studentOne, String studentTwo, String studentThree, String studentsTitles[])
{
this.moduleTitle = moduleTitle;
this.percentageCoursework = percentageCoursework;
this.percentageExam = percentageExam;
this.studentsList[0].name = studentOne;
this.studentsList[1].name = studentTwo;
this.studentsList[2].name = studentThree;
}
public void ShowDetails()
{
System.out.println("moduleTitle : " + moduleTitle +
"\n percentageCoursework : " + percentageCoursework +
"\n percentageExam : " + percentageExam +
+studentsList[0].name+studentsList[1].name+studentsList[2].name);
}
}
答案 0 :(得分:10)
"\n percentageExam : " + percentageExam +
+studentsList[0].name+studentsList[1].name+studentsList[2].name);
// ^
// ^ look! oh noes!
在最后一行的开头有一个额外的+
。
答案 1 :(得分:0)
percentageExam + +studentsList[0].name+studentsList[1].name
// ^^ Two "+" side by side.
