我用 Java 创建了一个二维数组，我正在寻找一种在控制台上打印它的方法，以便我可以确认我正在制作的东西是正确的。我在网上找到了一些为我执行此任务的代码，但我对代码的特定部分的含义有疑问。
int n = 10;
int[][] Grid = new int[n][n];
//some code dealing with populating Grid
void PrintGrid() {
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
System.out.print(Grid[i][j] + " ");
}
System.out.print("\n");
}
}
“\n”有什么作用？我尝试在谷歌上搜索，但由于代码很小，所以我找不到太多。
这是一条新线
