在java中使用System.out.printf显示商

Question

    float a, b;
    Scanner input = new Scanner(System.in);

    System.out.println("Enter 2 integer");
    System.out.println("Enter first integer");
    a = input.nextInt();
    System.out.println("Enter second integer");
    b = input.nextInt();
    System.out.println("Calculation the sum, difference, product, quotient "
            + "of 2 integer");
    System.out.printf("Sum of 2 integer is: %f\n", a + b);
    System.out.printf("Difference of 2 integer is: %f\n", a - b);
    System.out.printf("Product of 2 integer is: %f\n", a * b);
    System.out.printf("Quotient of 2 integer is: %0.2f\n", a / b);

这是我的代码和程序运行错误。所以我想像这样显示a = 7，b = 5所以a / b = 1.4

Answer 1

替换

System.out.printf("Quotient of 2 integer is: %0.2f\n", a / b);

与

System.out.printf("Quotient of 2 integer is: %.2f\n", a / b);
