编程java，生成以下等差数列的前十项：a0=1，an-a(n-1)=3，并保存到一个数组中。显示该数组的生成结果及其前五项之和。

Sure, here's the code to generate the arithmetic sequence and store it in an array:

int[] sequence = new int[10];
sequence[0] = 1;
for (int i = 1; i < 10; i++) {
    sequence[i] = sequence[i-1] + 3;
}

And here's the code to display the sequence and its first five terms' sum:

int sum = 0;
System.out.print("Sequence: ");
for (int i = 0; i < 10; i++) {
    System.out.print(sequence[i] + " ");
    if (i < 5) {
        sum += sequence[i];
    }
}
System.out.println("\nSum of first five terms: " + sum);

Hope that helps!
