add = (a, b) => a + b
const sum = numbers.reduce(add)sum of arrays numbers in java

String str = "a1b2c3d4";
char[] arr = str.toCharArray(); // stringi char array return etti.
System.out.println(Arrays.toString(arr)); // [a, 1, b, 2, c, 3, d, 4]
int sum = 0; // will contain sum of all digits
for(char each : arr ){ // '0'
if( Character.isDigit(each) ){
// isDigit(): identifies if the given character is digit
sum += Integer.parseInt(""+each); }
}
System.out.println(sum); // 10Copyright © 2021 Codeinu
