A simple example of using Scanner in java

/*
 * scanf(c)  == Scanner(java)
 *
 * int num;
 * char c1[100];
 * scanf("number? %d",&num);
 * scanf("string? %s",c1);
 *
 *
 *
 * char tmp[100];
 * int num;
 *
 * File *fp;
 * fp = fopen("aaa.txt","rb");
 * fgets(tmp,100,stdin);  //fgets(tmp,100,fp);
 * num = atoi(tmp);
 *
