例如,我想将数组u1与其他数组相乘?
HomeFragment homeFragment =
(HomeFragment)getSupportFragmentManager().getFragments().get(0);
答案 0 :(得分:1)
for(int i = 0; i < u1.length; i++)
{
u1[i] = value;
u2[i] = value;
//Etc
}
答案 1 :(得分:1)
这里我得到的但不完整:
public class Diff {
public static void main(String[] args) {
// TODO Auto-generated method stub
double[] u1 = {4,2,3,5,3,4};
double[] u2 = {3,0,2,4,2,3};
double[] u3 = {5,0,4,4,4,5};
double[] u4 = {0,1,2,4,2,3};
double[] u5 = {0,3,4,4,4,5};
double[] u6 = {3,1,0,4,2,3};
double[] u7 = {2,5,3,0,3,4};
double[] u8 = {3,1,1,4,2,3};
double[] u9 = {3,1,2,3,2,3};
double[][] u = {u2,u3};
for (int k=0; k < u1.length; k++){
for(int i = 0; i < u.length; i++)
{
for(int j = 0; j < u[i].length; j++){
System.out.println();
System.out.println(u1[k]*u[i][j]);
}
}
}
}
}

由于您的数组大小相同,因此只需一个索引就可以同时迭代所有数组,因此,在一个简单的for
cicle中,您可以一次访问和操作所有数组中的数据。在你的情况下,如果你想乘以u1和u2:
double multiply[] = new double[u1.length];
for(int i = 0; i < u1.length; i++){
multiply[i] = u1[i] * u2[i];
}
