Java - What does "\n" mean? [duplicate]

Question

I had created a 2-dimensional array in Java and I was looking for a way to print it out on the console so that I could confirm that the stuff I was making was correct. I found some code online that performed this task for me, but I had a question about what a particular bit of the code meant.

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");
    }
}

What does "\n" do? I tried searching on Google, but since it's such a small bit of code I couldn't find much.

\n 

This means insert a newline in the text at this point.

Just example

System.out.println("hello\nworld");

Output:

hello
world
