return index of element in array java code example
Example 1: get index of element in array java
System.out.println(new String(list).indexOf("e"));
Example 2: java array get index
public int getArrayIndex(int[] arr,int value) {
int k=0;
for(int i=0;i<arr.length;i++){
if(arr[i]==value){
k=i;
break;
}
}
return k;
}
Example 3: return matching index array java
public class compareArray{
public static void main(String[] args){
int[a] = {1,4,5,7};
int[b] = {6,4,3,7};
int[] ab = new int[4];
for(int i = 0; i<a.length; i++; )
{
if(a[i] == b[i])
{
int[] ab = new int[4];
Arraylist<Integer> al = new Arraylist<Integer>();
for(int i = 0; i < a.length; i++; )
if(a[i] == b[i])
{
al.add(a[i]);
}
}
Object[] c= al.toArray();
for(Object ob : c)
{
System.out.println(obj);
}
