Java Basic(29)-Summing Elements of Arrays

class apples{

public static void main(String args[]){

int bucky[]={21,16,86,21,3};

int sum=0;

for(int counter=0;counter<bucky.length;counter++){ →使用循環計算

sum+=bucky[counter];  →添加陣列元素

}

System.out.println("the sum of these number is " + sum);

}

}

添加數組元素是指使用循環添加：

bucky[0] + bucky[1] + bucky[2] + bucky[3] + bucky[4] = 21+16+86+21+3=147

該Program將運行這樣的：

the sum of these number is 147
