I am trying to print a multidimensional array filled with *s. here is the code.
String[][] star = new String[10][10];
for(String[] row: star)
{
Arrays.fill(row, "*");
}
System.out.println(Arrays.toString(star));
// prints something like 'Ljava.lang.String;@592fa617'
But I can't seem to print out what i want...what am I doing wrong?
try this
System.out.println(Arrays.deepToString(star));
You can use this:
for (int i=0; i<star.length;i++) {
for (int j=0; j<star[i].length;j++) {
System.out.println(star[i][j]);
}
}
Arrays by default don't print content.
Arrays.deepToString as suggested by other users. I am not sure how this is internally implemented though.You should use either the Arrays.deepToString method or foreach loops.
Well I can show you two ways to do it :
First Way :
for(int i=0;i<10;i++)
{
System.out.println();
for(int j=0;j<10;j++)
System.out.print(star[i][j]+"\t");
}
Second way :
java.util.Arrays.deepToString() which Returns a string representation of the "deep contents" of the specified array.
System.out.println(Arrays.deepToString(star));
