printstar列印星形圖案的java實現

public class PrintStar{
public static void main(String args[]){
System.out.println("\nCase 1:");
for(int i=0;i<8;i++){
for(int j=0;j<=i;j++){
System.out.print("*");
}
System.out.println();
}

System.out.println("\nCase 2:");
for(int i=0;i<8;i++){
for(int j=0;j<8;j++){
if(j>=i){
System.out.print("*");
}else{
System.out.print(" ");
}
}
System.out.println();
}
System.out.println("\nCase 3:");

for(int j=0;j<8;j++){
if(j>=8-i){
System.out.print(" ");
}else{
System.out.print("*");
}
}
System.out.println();
}

System.out.println("\nCase 4:");
