Explanation

match is used for matching operations, and its return value is of boolean type. Through match, you can simply verify whether a certain element exists in the list.

Example

// 验证 list 中 string 是否有以 a 开头的, 匹配到第一个,即返回 true
boolean anyStartsWithA =
    stringCollection
        .stream()
        .anyMatch((s) -> s.startsWith("a"));
 
System.out.println(anyStartsWithA);      // true
 
// 验证 list 中 string 是否都是以 a 开头的
boolean allStartsWithA =
    stringCollection
        .stream()
        .allMatch((s) -> s.startsWith("a"));
 
System.out.println(allStartsWithA);      // false
 
// 验证 list 中 string 是否都不是以 z 开头的,
boolean noneStartsWithZ =
    stringCollection
        .stream()
        .noneMatch((s) -> s.startsWith("z"));
 
System.out.println(noneStartsWithZ);      // true
