hey guys i'm having some trouble working this out. The aim is to convert an int array like this {1, 2, 3, 4} by adding one to each element and printing it using an ENHANCED for loop, so it will look like this {2, 3, 4, 5}. This is what i got so far :
int myArr[] = {1, 2, 3, 4};
for (int i: myArr){
i =+1;
myWindow.writeOutLine(i);
}
Pretty sure that is not close, i'm unsure how to store the new value in the array and go to next.
You can't do it with the enhanced for loop, since that loop hides the indices of the array, so you can't modify the array.
Use a traditional for loop instead.
for (int i = 0; i < myArr.length; i++) {
myArr[i]++;
myWindow.writeOutLine(myArr[i]);
}
you can use separate index variable if you have to use enhanced loop.
int myArr[] = {1, 2, 3, 4};
int count = 0 ;
for (int i: myArr){
myArr[count] = i+1;
myWindow.writeOutLine(myArr[count]);
count++;
}
int[] myArr = {1, 2, 3, 4};
for(int i = 0; i < myArr.length; i++){
int x = 1; // Amount to increment each value by
myArr[i] = myArr[i] + x;
}
System.out.println(Arrays.toString(myArr));
