本文主要是介绍java通过传参打印杨辉三角等腰，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
public class YH {
public void yangHuiTriangle(int s){
/* System.out.println("请输入行数：");
Scanner sc = new Scanner(System.in);
s=sc.nextInt();*/
//创建二维数组
int triangle[][] = new int[];
//遍历二维数组的第一层
for(int i=0;i<triangle.length;i++){
//初始化第二层数组的大小
triangle = new int[i+1];
//打印正三角n行要满足每一行比上一行少一个*
int num=triangle.length-i;
for(int z=0;z<num;z++){
System.out.print("*");
}
//遍历第二层数组
for(int j=0;j<triangle.length;j++){
//两层的数组元素复制为1
if (i==0||j==0||j==triangle.length-1){
triangle[j] = 1;
}else{
//其他数值通过公式计算
triangle[j] = triangle[i-1][j]+triangle[i-1][j-1];
}
System.out.print(triangle[j]+" ");
}
System.out.println();
}
}
public static void main(String[] args) {
YH yh = new YH();
yh.yangHuiTriangle(10);
}
}
运行结果如下：
