How do you define a Java array whose entries are also Java arrays?

The easiest method is to define a two-dimensional array and assign each member as follows:
// define two-dimensional array
Object[][] objArr = new Object[5][3];
// assign values to array
for (int i = 0; i < objArr.length; i++)
{
objArr[i] = new Integer[3];
for (int j = 0; j < objArr[i].length; j++)
{
objArr[i][j] = new Integer((i + 1) * (j + 5));
}
}
// display results
for (int i = 0; i < objArr.length; i++)
{
for (int j = 0; j < objArr[i].length; j++)
{
System.out.println("objArr[" + i + "][" + j + "] = " + objArr[i][j]);
}
}
