java中的嵌套while循环不工作
用户输入java中的嵌套while循环不工作,java,Java,用户输入 5 所需输出(使用while循环) 代码: while(temp1内部while循环后temp2的值将是a+1。由于您以后没有将其重置为1,您将不会再次进入此内部循环,因为下面的条件while(temp2代码注释解释了代码的错误 //assume temp1 equals 1 while(temp1 <= a){ temp2 = 1;//you're primarily forgetting to reset the temp2 count while(temp

所需输出(使用while循环)
代码:
while(temp1内部while
循环后temp2
的值将是a+1
。由于您以后没有将其重置为1
,您将不会再次进入此内部循环,因为下面的条件while(temp2代码注释解释了代码的错误
//assume temp1 equals 1
while(temp1 <= a){
temp2 = 1;//you're primarily forgetting to reset the temp2 count
while(temp2 <= a){
temp = temp1*temp2;
System.out.print(temp + " ");
temp2++;
}
temp1++;
System.out.println();
}
//假设temp1等于1
while(temp1)
有了这个答案,您不需要重置temp变量,如果我必须将问题分解为简单的单词,您将产生所需的结果
- 用户将输入一个数字:“x”
- 创建一个大小为arr[x][x]的二维矩阵
- 每个元素的值都将是a[i][j]=i*j;//考虑(i=1;i
inta=5;//或者以其他方式获得此值。
//初始化你的值
int temp1=1;
int temp2=1;
int temp;//这里只需要一个声明。
而(temp1用于(int i=1;i它是如何工作的?输出是否错误?请发布整个函数,这只是其中的一部分。例如,您正在将内容分配给temp,但temp没有声明为什么您不使用for
循环?或者您的调试器来调试您的代码?我怀疑temp2
应该在某个地方重置为1。我不知道是谁对此投了反对票,但他给出了输入、预期输出和所需代码。他唯一缺少的是实际输出。@ArkaBhattacharjee没问题:)很高兴我能帮上忙。
