如何在jdk8中像这样使用for循环。

for (ClassAttendanceParent classAttendanceParent : list) {
                TransportAttendanceFormBean tb = new TransportAttendanceFormBean();
                tb.setDate(classAttendanceParent.getAttendancedate().toString());
            }

in JDK8(如何转换上述for循环)

list.forEach((ClassAttendanceParent element) -> System.out.println(element.getAttendancedate()));

试试这个

list.forEach(element->{
        TransportAttendanceFormBean tb = new TransportAttendanceFormBean();
        tb.setDate(element.getAttendancedate().toString());         
    });

或(无需在每次迭代中创建新对象)

TransportAttendanceFormBean tb = new TransportAttendanceFormBean();
  list.forEach(element->{   
        tb.setDate(element.getAttendancedate().toString());         
    });
