Solution 1

String str="sdfvsdf68fsdfsf8999fsdf09";
String numberOnly= str.replaceAll("[^0-9]", "");

update:

String str="fgdfg12°59'50\" Nfr | gdfg: 80°15'25\" Efgd";
String[] spitStr= str.split("\\|");
String numberOne= spitStr[0].replaceAll("[^0-9]", "");
String numberSecond= spitStr[1].replaceAll("[^0-9]", "");

Solution 2

public static String getOnlyNumerics(String str) {
    if (str == null) {
        return null;
    }
    StringBuffer strBuff = new StringBuffer();
    char c;
    for (int i = 0; i < str.length() ; i++) {
        c = str.charAt(i);
        if (Character.isDigit(c)) {
            strBuff.append(c);
        }
    }
    return strBuff.toString();
}

Solution 3

public static int extractNumberFromAnyAlphaNumeric(String alphaNumeric) {
    alphaNumeric = alphaNumeric.length() > 0 ? alphaNumeric.replaceAll("\\D+", "") : "";
    int num = alphaNumeric.length() > 0 ? Integer.parseInt(alphaNumeric) : 0; // or -1 
    return num;
}

You can set the value to 0 or -1 (what to do if no number is found in the alphanumeric at all) as per your needs
