Help with java Int Parse and arrays?

Hello there, I’m just beginning in Java so We were looking for those help.I’m speculated to create software which asks a user for any string with integers.Including “123sdf1564fd34.” We are then purported to use a good Integer Parse strategy to take that integers out of your string and display these individuals on individual lines.Thus for my own example, it becomes 123, 1564, along with 34.I will be supposed in order to write a technique like criminal court static int intParse(String s) this returns range, but We are not convinced how to achieve this.Any help could well be appreciated.
The best way would WHEN I write the particular method

public static int intParse(String s)

int cn=0, my partner and i;
for(i=0; i<s.length(); i++)

if(Character.isDigit(s.charAt(i)))
cn++;

int ar=new intcn;
cn=0;
for(i=0; i<s.length(); i++)

if(Character.isDigit(s.charAt(i)))

arcn=change(s.charAt(i));
cn++;

give back ar;

now change functionality to convert char in order to int
int change(char ch)

int ans;
switch(ch)

situation ‘0’:ans=0;
separate;
situation ‘1’:ans=1;
separate;
//same manner

give back ans;
