这是基本的编程,但我仍然不完全确定如何每隔5行创建一个空白行。请帮忙!谢谢!
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("please enter an integer for the length");
int theLength = input.nextInt();
System.out.println("Please enter an integer for the height");
int theHeight = input.nextInt();
System.out.println("Please enter a character");
String character1 = input.next();
// int character = Integer.toString(character1);
for (int i = 0; i < theHeight; i++) { //the outer loop controls the row
for (int j = 0; j < theLength; j++) {// inner loop control
if (j % 6 != 0) { //creates a space for ever 5 character
System.out.print(character1 + " ");
} else System.out.print(" ");
}
System.out.println();
}
}

如果我理解了您的问题,您可以将else
从print(" ")
更改为println
;像
if(j%6!=0){ //creates a space for ever 5 character
System.out.print(character1 + " ");
} else {
System.out.println();
}

println("...")
方法打印字符串并将光标移动到新行,但print("...")
方法只打印字符串,但不会将光标移动到新行。
希望它有所帮助!

您的循环基于零,因此第0行也可以被5整除:如果符合您的条件,则按如下方式修改for循环:
for (int i = 0; i < theHeight; i++) { // the outer loop controls the row
for (int j = 0; j < theLength; j++) {// inner loop control
if (i % 5 != 0) { // creates a space for ever 5 character
System.out.print(character1 + " ");
} else {
System.out.print(" ");
}
}
System.out.println();
}

如何为每第5行打印一个空行?
根据您的代码,在我看来,您希望在每个 n 字符后创建一个空行,而不是在 n 行..
无论您想要在n行或列之后打印空格或换行符,您只需要一个循环。
每5个字符打印一个换行符:
int height = 3, length = 5;
String myChar = "A";
for(int x=0; x<height * length; x++){
System.out.print(myChar + " ");
if( (x+1) % length == 0) // (x+1) so the it won't print newline on first iteration
System.out.println();
}
height * length
获取要打印的字符总数(x+1)
,因为您的x从0
和0 % 0 = 0
开始。<强>输出:强>
A A A A A
A A A A A
A A A A A
