程序代码：
public class Triangle {
public static void main(String[] args) {
printTriangle(5);
}
public static void printTriangle(int line) {
for (int i = 0 ;i <= line ;i++) {
for (int j = 0; j < line - i; j++)
{
System.out.print(" ");
}
for (int x = 0;x < 2*i-1; x++ )
{
if(x%2==0)
System.out.print("*");
else
System.out.print(" ");
}
System.out.println();
}
}
}
public static void main(String[] args) {
printTriangle(5);
}
public static void printTriangle(int line) {
for (int i = 0 ;i <= line ;i++) {
for (int j = 0; j < line - i; j++)
{
System.out.print(" ");
