如何在数组的对应位置打印这些数字？

Question

import java.util.*;

public class PracticeFinal {
   public static void main (String[] args) throws FileNotFoundException{
       Scanner input = new Scanner (new File("altitude.txt"));
       int[] x = new int [400];

       altitude[0] = 0;
       int i = 0;
       System.out.println("x\ty\taltitude");
      while (input.hasNextFloat()) {
          int line = input.nextInt();
          x[i]=line;
          int line2=input.nextInt();

       int ind=0;
       for(int i=0;i<100;i++)
       {
           if (altitude[i]>max)

   public static void printAverage(float []altitude){
       float total = 0;
       for(int i=0;i<100;i++) 
       {
           total += altitude[i];
        }
        float avg = total / 100;
        System.out.printf("The aveage altitude of the region is " + "%.2f", avg);
        System.out.println();
   }
   public static void printContour(float []altitude, int[]x, int[]y){

我在这个程序的最后一部分需要帮助，有一个 x 和 y 图表，高度为 ex, 0,0 = 109.1 1,0= 200 因此，对于最后一种方法，我需要在其相应位置打印出从 1,1 到 2,1 到 3,1 的高度，依此类推 在for循环之后不知道下一步该做什么 这是我读取的文件，第一个数字是 x，第二个是 y，第三个是高度。

public static void printContour(float []altitude, int[]x, int[]y){
   for (int i = 0; i < 100; i++) {
        for (int a = 0; a < 100; a++) {
            if (x[i] <  x[a]) {
                int temp_for_x = x[i];
                x[i] = x[a];
                x[a] = temp_for_x;
                int temp_for_y = y[i];
                y[i] = y[a];
                y[a] = temp_for_y;
                float temp_for_alt = altitude[i];
                altitude[i] = altitude[a];
                altitude[a] = temp_for_alt;
            }
            if(y[i] < y[a]){
                int temp_for_x = x[i];
                x[i] = x[a];
                x[a] = temp_for_x;
                int temp_for_y = y[i];
                y[i] = y[a];
                y[a] = temp_for_y;
                float temp_for_alt = altitude[i];
                altitude[i] = altitude[a];
                altitude[a] = temp_for_alt;
            }
        }
    }

    for (int incr=0;incr<100;incr++) {
         System.out.print(x[incr]+ "   " + y[incr] + "   " + altitude[incr]+ "   ");
         if(incr%10 == 9)
            System.out.println();

   }
