How do I convert a string like:
"114 214 219"
Into an an int array so I have something like this stored in my int array:
int[] couseNumbers = int[3];
for(int i = 0; i < 3; i++){
courseNumbers[i] = Integer.parseInt(/*get int in the string array*/);
}
Split the String into an array first.
String[] stringArray = "114 214 219".split(" ");
Then in the loop you can access that array:
courseNumbers[i] = Integer.parseInt(stringArray[i])
Try this
String s = "1 2 3";
String array[] = s.split(" "); //Splits the Array by spaces
int a[] = new int[array.length]; //Makes new int array
for(int i=0;i<a.length;i++){
a[i] = Integer.parseInt(array[i]); //Converts String to int
}
Using Java 8 streams.
List<Integer> courseNumbers = Arrays.stream("1123 213 23"
.split(" ")).map(x-> Integer.parseInt(x))
.collect(Collectors.toList());
Answer above by Eduardo Dennis will not work as string cannot convert to int directly. You can do something like this.
public static void main(String []args){
String s = "114 214 219";
String [] courseNumbers = s.split(" ");
Integer [] intArray = new Integer[courseNumbers.length];
for(int i= 0; i < courseNumbers.length; i++){
intArray[i] = Integer.parseInt(courseNumbers[i]);
}
}
