如何在for循环中只打印一个输出?如果数字在数组中,那么它将打印 "Present"
但如果数字不在数组中,它将打印出来 "Nope"
. 我需要搜索用户输入的号码。
Scanner in = new Scanner(System.in);
int numOfLoop = in.nextInt(); // How many loop I want.
int[] num = new int[numOfLoop];// Array of the numbers.
for (int i = 0; i < numOfLoop; i++)// getting the numbers.
{
num[i] = in.nextInt();
}
int searchNum = in.nextInt();// The number that is to be search.
for (int i = 0; i < numOfLoop; i++)// For loop to search the number in the array.
{
if (num[i] == searchNum) {
System.out.println("Present");
}
if (searchNum != num[i]) {
System.out.println("Nope");
}
}
输入:
5 //How many iteration I want
3 21 2 5 23 //Input 5 Number
2 //Number to be searched
输出:
Nope
Nope
Present
Nope
Nope
预期产量: Present

您需要在循环外维护一个变量,并使用该变量在循环外打印,如下所示:
添加了java 8解决方案:
如果您使用的是java8或更高版本,那么还可以使用stream来替换上面的for循环。具体如下:
uidvcgyl2#
你在正确的轨道上。你只需要在条件语句中添加其他内容
