JAVA中怎么编写打印功能代码

Print.java java Print 自己运行一下 from:
采纳哦
怎样用Java代码打印并输出如下图形
这样可以
public static void main(String[] args) {
String[] temps = {"A","B","C","D","E","F","G"};
for (int i = 1; i = temps.length; i++) {
for(int j = temps.length; j i; j--){
System.out.print(" ");
}
for (int j = 0; j i*2-1; j++) {
System.out.print(temps[i-1]);
}
System.out.println();
}
}
运行结果

DDDDDDD
EEEEEEEEE
