java - 允许用户输入字符串和整数

Question

允许用户输入文本和整数的代码是什么。我正在创建一个 GPA 计算器，程序会询问用户正在学习的课程，然后将其存储为变量。例如。“微积分 12。” 我能够通过使字符串和整数成为两个单独的变量来解决这个问题。我将如何做到这一点，以便用户可以输入“Calculus 12”并将整个内容存储为变量而没有问题？

    System.out.println("For the next set of questions, please answer without typing in a number. ");
    System.out.println("For example, 'Pre-Calculus'. ");

    System.out.print( name + ", What is the 1st course are you taking? ");
    course1 = keyboard.next();

    System.out.print("What level is it? Type in a value: ");
    num1 = keyboard.nextInt();

Answer 1

使用keyboard.nextLine() 而不是keyboard.next()。
