将一维数组的值应用于二维数组的.NumberFormat的代码

import java.text.NumberFormat;

public class ArrayFormatting {
    public static void main(String[] args) {
        double[] oneDimensionalArray = { 10.12345, 20.6789, 30.9876 };
        double[][] twoDimensionalArray = new double[3][3];

        NumberFormat numberFormat = NumberFormat.getInstance();
        numberFormat.setMaximumFractionDigits(2); // 设置小数点后最多保留两位

        for (int i = 0; i < oneDimensionalArray.length; i++) {
            twoDimensionalArray[i][0] = oneDimensionalArray[i];
            String formattedValue = numberFormat.format(oneDimensionalArray[i]);
            twoDimensionalArray[i][1] = Double.parseDouble(formattedValue);
        }

        // 输出二维数组的值
        for (int i = 0; i < twoDimensionalArray.length; i++) {
            for (int j = 0; j < twoDimensionalArray[i].length; j++) {
                System.out.print(twoDimensionalArray[i][j] + " ");
            }
            System.out.println();
        }
    }
}
