I have a binary file with coordinates in Latitude and Longitude how can
I convert then to degrees?

Byte 180-183 (Latitude)
Hex 119c67 integer 18418791
Byte 184-187 (Longitude)
Hex 0fbe72 integer 16508674
Decoded Decimal: Latitude 30.697985
Longitude 27.514457

yeah!
but how to get integers when I use hex to integer :
System.out.println("Hex to Integer"+ Integer.valueOf("0fbe72",
16).intValue());
I'm getting - 1031794????
any ideas????

or
String hexVal = "119C67";
System.out.println("Hex to Decimal. Hex = "+ hexVal + ",Decimal =
"+Integer.parseInt(hexVal,16));

I'm getting 1154151
?????

Are you sure you got the bytes right?
decimal 16508674 = hex 00FBE702 00 FB E7 02
decimal 18418791 = hex 01190C67 01 19 0C 67

See the example here.

However - even if that functionality were not built in, parsing a hex number
should be trivial with a simple for loop. Perhaps you should write it for
practice.

Something like this perhaps (note - I have not compiled or tested this)

int parseHex(String x){
int ret = 0;
for(char c : x.toCharArray()){
ret*=16;
if(c>='a'&&c<='f')
ret+=c-'a'+10;
if(c>='A'&&c<='F')
ret+=c-'A'+10;
if(c>='0'&&c<='9')
ret+=c-'0';
else
return 0; //error handling?
}
return ret;
}
