如何查看列表中的下一项?当我使用这段代码时,它总是为空
if (recno!=0){
System.out.print("\n\n\t\t\t\t Next Record");
System.out.print("\n\n\t\t\t Employee Number: "+EmpNo[1]);
System.out.print("\n\t\t\t Employee Number: "+EmpName[1]);
System.out.print("\n\t\t\t Salary: : "+Salary[1]);
System.out.print("\n\n\t\t Do you want to see the next record ? [press n]");
next = reader.readLine();
if(next!="y"){
recno++;
System.out.print("\n\n\t\t\t Employee Number: "+EmpNo[recno]);
System.out.print("\n\t\t\t Employee Name: "+EmpName[recno]);
System.out.print("\n\t\t\t Salary: "+Salary[recno]);
}
}
else{
System.out.print("\n\n\t\t\t\tRecord Not Found!");
}
答案 0 :(得分:1)
这肯定有助于在这里使用equals:
if(! "y".equals(next) ){
