写一个爱心代码，java

public class Heart {
public static void main(String[] args) {
int rows = 6;
int columns = 7;
String[][] heart = new String[rows][columns];

for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {
heart[i][j] = " ";
}
}

for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {
if ((i == 0 && j % 3 != 0) || (i == 1 && j % 3 == 0) || (i - j == 2) || (i + j == 8)) {
heart[i][j] = "*";
}
}
}

for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {
System.out.print(heart[i][j]);
}
System.out.println();
}
}
}

//输出结果
