Oh! I have a trick for arrays too. lets assume we have an array named arr then for(i:arr) { System.out.println(i);//Here i have just printed the elements but you can do anything } //Here each time when the loop runs the i contains the next element of the array cell which means if arr[] would be{1,7,10,99,-10} i will have the value 1 in first execution of the for loop then i will have value 7 in next loop and so on.... comment if you liked? NOTE:Strictly not for exam purpose |

into m,n,p,q= 0; for(m=2;m<=3;++m) { for(n=1;n<=m;++n) { p=m+n; if(p%3==0) q=q+p; else q=p+4; } } System.out.println("Q="+q); |

Guys all of you must have faced the problem of printing a particular array as it requires the user to type out another for loop which is time consuming tedious and boring heres a trick but u ll have to import java's utilility package by import java.util.* just say u wanna print array named arr type :- System.out.println(Arrays.toString(arr)); the output is like this : [a,b,c,d] try this one out |

Just thought I would share as a similar question came in our prelims : String s = "hi"; System.out.println(s.indexOf("1")); Output for this is -1 |
