How To Shuffle String Arrays

How Can I Shuffle below array

String[] firstName =["a","b","c","d","e"];
String[] lastName =["p","q","r","s","t"];
String[] salary =["10","20","30","40",50"];
String[] phoneNo= ["1","2","3","4","5"];

after shuffling the array i need result like

String[] firstName =["d","b","e","c","a"];
String[] lastName =["s","q","t","r","p"];
String[] salary =["40","20","50","30",10"];
String[] phoneNo= ["4","2","5","3","1"];

means for example if index of "a" from firstName Changes from 0 to 4, respective index of "p","10","1" to be changed from 0 to 4..
