如何将两个数字之和放在“=”旁边

Question

I want to display the sum of two numbers beside the equal sign.

    Scanner scan = new Scanner(System.in);
         int i ;
            System.out.println("enter a number: " );
            i = scan.nextInt();
            int a = i - 1  ; 
            while(a >= 1){
                System.out.println(i +" + "+ a + " = " );

//i want to display the sum of two numbers beside the equal sign.

               i =i + a ;
                System.out.println(i);
                a --;


//  how can I display the answer beside the equal sign?

            }
      } 
    }

How can I display the answer beside the equal sign?

Answer 1

将您的第一个println更改为print 。

Answer 2

As per your question I think you are most probably asking how we can show the sum of two numbers in the print statement. So in your code after "=" you just need to add (i+a) this will sum the value of i and a. System.out.println(i +" + "+ a + " = " + (i+a)) .

I hope this answers your question.

Answer 3

System.out.println() method prints a "newline character" ( \\n ) right after its' input.

There is another method that does not do this:

System.out.print()

You should change

System.out.println(i +" + "+ a + " = " ); to

System.out.print(i +" + "+ a + " = " ); this.
