Answer 4

similar like this

int rows = 5;
String spaces="", stars1="", stars2="";
for(int i=rows; i>=1; --i) { //all rows

stars1 = "* ".repeat(i); // for 2 (j: 5..9, 4..7, 3..5, 2..3, 1..1)
stars2 = "* ".repeat(i-1); // for 3 (j: 0..3, 0..2, 0..1, 0..0)

System.out.println( spaces +stars1 +stars2);

spaces += " "; // for 1
}
