級聯在Java中沒有像預期的那樣工作

Question

當我輸入「little code」作爲輸入（在最後一行）時，我期望輸出「我寫了一小段代碼」（在最後一行），但輸出是「我寫了一個「 這是我的代碼：`

String s = "I wrote a "; 
int i = 4; 
double j = 7.0; 
Scanner scan = new Scanner(System.in); 
String c; int a; double b; 
a = scan.nextInt(); 
b = scan.nextDouble(); 
c = scan.nextLine(); 
System.out.println(i + a); 
System.out.println(j + b); 
System.out.println(s + c); 
scan.close(); 

Answer 1

這段代碼是對我工作的罰款：

String s = "I wrote a "; 
int i = 4; 
double j = 7.0; 
Scanner scan = new Scanner(System.in); 
String c; int a; double b; 
a = scan.nextInt(); 
b = scan.nextDouble(); 
scan.nextLine(); 
c = scan.nextLine(); 
System.out.println(i + a); 
System.out.println(j + b); 
System.out.println(s + c); 
scan.close(); 

只是缺少scan.nextLine（）後，b = scan.nextDouble （）;
