I get a strange problem on some android phone , when I run the code under.
public void test(){
int num = 1;
for(int i=0;i<14;i++){
num = num+100000;
}
System.out.println("num "+num);}
I expect the answer "1400001",but I get the wrong answer "200385" on the
phone like MotoX 2ndGen , Xiaomi3,Xiaomi note etc. what's the strangest
things is I can get the right answer when I want to debug it ,or complicate
the code like
public void test(){ int num = 1; for(int i=0;i<14;i++){ num = num+100000;
System.out.println("num "+num); } }
public void test(){ int num1 = 1; for(int i=0;i<14;i++){ num1 =
num1+100000; } System.out.println("num1 "+num1); int num2 = 1; for(int
i=0;i<14;i++){ num2 = num2+100000; } System.out.println("num2 "+num2); }
or turn int to long ,or make "100000" to 100, it can get the right answer
usually.So what the truly reason occur? int overflow? Thank you.
