int[] numbers = new int[5]; .. System.out.println(numbers[0]); That would print 0 as well. An array of integers without setting a value will have 0 by default.<\/p>\n

If you receive x = 480, y = 360, num2 = 2<\/code> (we don’t know num1), lets assume num1=1<\/p>\n

X[num1-1] = x;\nY[num1-1] = y;\n<\/code><\/pre>\n
this would be<\/p>\n
X[1-1] = x; \/\/X[0] = 480
\nY[1-1] = y; \/\/Y[0] = 360<\/p>\n
Now…<\/p>\n
   while(i <= num2) {\n        System.out.println(X[0]+\" \"+Y[0]+\" \"+X[1]+\" \"+Y[1]);\n        i++;\n    }\n<\/code><\/pre>\n
Here you are always printing the same values regardless of i, so if you have not yet set a value for those elements then they will always be 0.<\/p>\n
There you will print 480, 360 and then 0, 0 since you only have set values for the array in the position 0. The ones in the position 1 are not yet set, 0 by default.<\/p>\n
I don’t know what do you mean by: next output equals 0 0 30 360<\/code><\/p>\n
But maybe you wanted something like this…<\/p>\n
...\n<\/code><\/pre>\n
\/\/If num1 is 1 then it will fill up X[0] and X[1] with x.
\n        X[num1-1] = x;
\n        Y[num1-1] = y;<\/p>\n
    X[num1] = x;\n    Y[num1] = y;\n..\n           \/\/ Out of bounds risky here, make sure you have enough elements before calling i+1 index.\n            System.out.println(X[i]+\" \"+Y[i]+\" \"+X[i+1]+\" \"+Y[i+1]);\n...\n<\/code><\/pre>\n
But make sure you don’t cause an out of bounds.<\/p>\n
Now, if you sent num1=2 then <\/p>\n
X[2-1] = x; \/\/X[1] = 480\nY[2-1] = y; \/\/Y[1] = 360\n<\/code><\/pre>\n
There you are not setting the value for the element with index 0, so it will preserve the default value, 0.<\/p>\n<\/p><\/div>\n
