text: Linear Search | Java code for linearly searching x in arr [ ] . If x is present then return its location , otherwise return - 1 ; Driver code ; Function call
code: class GFG { public static int search ( int arr [ ] , int x ) { int n = arr . length ; for ( int i = 0 ; i < n ; i ++ ) { if ( arr [ i ] == x ) return i ; } return - 1 ; } public static void main ( String args [ ] ) { int arr [ ] = { 2 , 3 , 4 , 10 , 40 } ; int x = 10 ; int result = search ( arr , x ) ; if ( result == - 1 ) System . out . print ( " Element ▁ is ▁ not ▁ present ▁ in ▁ array " ) ; else System . out . print ( " Element ▁ is ▁ present ▁ at ▁ index ▁ " + result ) ; } }
