java foreach example

Example 1: foreach java

for (String name : names) {
    System.out.println(name);
}

Example 2: java foreach

List<String> someList = new ArrayList<String>();
// add "monkey", "donkey", "skeleton key" to someList
for (String item : someList) {
    System.out.println(item);
}

Example 3: javascript foreach example

var colors = ["red", "blue", "green"];
colors.forEach(function(color) {
    console.log(color);
});

Example 4: inline foreach java

names.forEach(name -> System.out.println(name));

Example 5: loop in java 8

List<Integer> data = new ArrayList<>();

//Indexed Loop
for(int i = 0,size=data.size();i<size;i++){
	System.out.println(data.get(i));  
}

//For each loop
for(Integer element : data){
	System.out.println(element);
}

//Using forEach
data.forEach(System.out::println);

//Using Stream
data.stream().forEach(System.out::println)
  
//While loop
int i = 0;
while(i<data.size()){
	System.out.println(data.get(i++));  
}

Example 6: for-each loop in java

// syntax
for(<DataType of array><variablename> : <Array to be iterated>)
{
   // code
}
